Sgurgola is a graceful
small Italian village laying on the slopes
of Lepini Mountains, dominating the Sacco river valley. The village
lies in Ciociaria (pronounced Chow-Chah-Reea), the historical
area approximately corresponding to the province of Frosinone,
in the region Latium.
Until 1927, before the province of Frosinone was founded, the
village belonged to the province of Rome.
Sgurgola is about 24 kilometers (15 miles) away from Frosinone
and about 70 kilometers (45 miles) from Rome.
History
The tradition tells the village was founded by Spartacus, the
Thracian gladiator who led a slave uprising in 73-71 BCE (Third
Servile War): this would explain the rebellious temperament which
was ascribed (at least in the past) to the Sgurgolan people, which
during the fascism period had many victims of political persecutions.
More likely the village was founded at the time of barbarian invasions,
as a shelter for the peoples of Anagni, Ferentino and other villages
of the environs, since its protected position allowed to control
the valley below.
The ancient name of the village was actually Sculcula,
that could be a diminutive for the Late Latin (6th Century
CE) word sculca, meaning "look-out", which gave
origin to the Italian word "scolta" or "scolca"
in its turn derived from the gothic word skulks, meaning
"sentry, guard" (Camilleri-De
Mauro).
According to others
the name could come from the many springs that gush out (in Italian
"sgorgare") from the limestone on which the village
is built; in this case the etymology could be the same of Gorga,
a village laying on the opposite slope (the one in the province
of Rome) of the Lepini Mountains, just behind Sgurgola.
In a text of 1741, reported in 1859 by Silvestri, the road that
connects Terni to the Marmore waterfall and continues to Rieti
is called the Sgurgola (or Scurgura) road, while mention is also
made of the Sgurgola mountains. Furthermore, the Abruzzese town
of Scurcola Marsicana, in the province of L'Aquila, is well known.
In the Capitanata area of Apulia, in the province of Foggia, in
Dragonara diocese, currently in the territory of Casalnuovo Monterotaro,
the San
Matteo di Sculgola monastery rises up, which was one of the
properties of Santa Maria del Gualdo abbey in Mazzocca. In the
province of Foggia as well, in Casalvecchio
di Puglia municipality, in the Northern Daunian Mountains,
the "Casone della Sgurgola" can be seen, a square plan
fortified tower, which rises up along the provincial road linking
Casalnuovo to Torremaggiore.
Actually Sgurgola's area was inhabited since the oldest ages,
as testified by the rock-out chamber tomb attributed to the Rinaldone
culture, in Chalcolithic age (III Millennium BCE), of a man of
about 30 years of age, found in 1880 in a cave near the railway
station.
The remains are now exposed
at the Museo delle Civiltà (Museum of Civilizations) section
Preistorico Etnografico Luigi
Pigorini" in Rome, along with their grave
goods, including flintstone arrowheads with tang, some of
which painted with cinnabar, a stone axe-hammer, ogival heeled
copper dagger and a small earthenware (impasto) flask-shaped
pot. Also the cheek and upper jaw bones of the skull
were tinted with cinnabar. This is an evidence of rituals following
the burial and the decomposition of the corpse.
In the historical age the area in which today Sgurgola lies was
occupied by the Volsci, an Italic population who was subdued by
the Romans in the fourth century B.C., while in the Roman age
in the valley of river Sacco (then named Trerus or Tolerus)
between Sgurgola and Anagni, lied the so-called Compitum Anagninum,
the crossroads between via Latina and via Labicana, quoted also
by Titus Livy, who probably was in the area of the present hamlet
of Osteria della Fontana, in Anagni municipality. In the same
area there was also a lake, named Bassano or Clarano, which was
there also in historical age
(S. Gatti).
From Osteria della
Fontana a road began, whose route is partly followed by present
via Morolense, that crossed Sacco valley where, due to the fertility
and flat configuration of the land and availability of water,
many production and dwelling settlements developped, at least
from the middle republican age. At Casalini, near the railway
station, about 1908, during the execution of farm works on the
Posta counts' estates a clay roof tile
was found, bearing the kilnman's stamp (Princeps, Pomponius
Corvus' servant). The fact that in the area it was easy to
find fragments of clay objects, make us think that the kiln they
came from was just around there
(G.
Gatti).
In Villamagna,
not far from the railway station, the ruins of a Roman imperial
villa of the late imperial age can be seen, which lodged Emperor
Antoninus Pius and his adopted son Marcus
Aurelius, Emperor-to-be, who told in a letter about his stay
in the villa (see my webpage).
The oldest written data about Sgurgola can be found in Papal bull
issued by Urban II on August 21st 1088, where the castle named
Castrum Sculcule was alloted Pietro, bishop
of Anagni, with other castles of the area, including that of "Villam
Magnam. Pietro bestowed the castle as a fief to the
Counts of Ceccano.
The history of Sgurgola is marked by several rule turns between
the different feudal families: counts of Ceccano, Torellis, Caetanis and Colonnas.
An evidence of habitual visiting of Sgurgola by the Caetanis is
given by the fact of July 13th 1159, when Pietro Caetani went
to Sgurgola castle with cardinal Boso and Ruggero the nephew of
pope Alexander VI's Chancellor in order to get an oath of allegiance (Paravicini Bagliani, pag. 7). In
April 1300 Sgurgola hosted a meeting between pope Boniface VIII
and emissaries of king of England Edward
I Plantagenet, to try to mediate in wars against France and
Scotland
(Dupré
Theseider).
Sgurgola was later the target of a real campaign of purchases
by the Caetanis, and in particular by Pope Boniface
VIII, born Benedetto Caetani, native of Anagni, due to its
strategic position, overlooking the Sacco valley and facing Anagni.
The importance of these purchases is proven by the four papal
bulls issued on 1st July, 1300, regarding the castle,
and its purchase by Pietro Caetani, Count of Caserta and pope's
nephew, who took it over from archbishop Adinolfo of Supino, heir
of Simone of Sgurgola, and from the nuns of the monastery of Santa
Maria in Viano (Giammaria). Many of the properties, in Sgurgola
or elsewhere, acquired by the pope's relatives, were sold at a
low price or donated, with the hope of arousing the pope's benevolence.
According to the Colonnas, and their associates, the castle and
other properties were acquired by the Caetanis as a result of
threats and violence of the papal courts, with actions aimed to
sow dissension between the two co-owner brothers
(Paravicini
Bagliani, pag. 138).
This would be in agreement with the accusations hurled by Jacopone da Todi against Boniface: "Quando
nella contrata, taiace alcun castello / n estante
mitti screzio enfra frate fratello; / allun getti
el braccio en collo, allaltro mustri el coltello / se no
nassente al tuo appello, menaccili de firire" ("When
in the neighbourhood, you ever like a castle / t once you
sow discord between brother and brother; / one of them you hug,
to the other show a knife / if he doesn't agree to your call,
you threat him you will wound"). The brothers Giordano,
Gualgano and Pietro, heirs of the lords of Sgurgola, continued
to occupy the castle, until they were expelled by the judgment
of 21st April, 1300, issued by Giacomo
of Ransano, Vicar-General of Campagna and Marittima. The pope
sealed the conquest of Sgurgola with a visit and with the promulgation
of two bulls, on 23rd and 25th
August, dated exactly from the village (Giammaria).
The clash between these
two last families was one of the causes of 1303 events which led
to the "Anagni slap";
the tradition says that in 1303 Sgurgola was the scene of some
of these events. On the same day of the outrage, the brothers
Peter and Galgano of Sgurgola, who were among the conspirators,
would have regained Sgurgola castle, which had been taken from
them three years before (Giammaria).
The Bonifacio palace at Anagni, where the outrage would happen,
probably belonged to Corrado of Sgurgola (Fedele, 1921a).
In 1314 Pietro Caetani conquered Sgurgola for his family, who
owned it until 1484, when Prospero
Colonna conquered it. The Colonna family ruled Sgurgola until
1818.
Sgurgola is represented
in one of the maps ("Latium et Sabina") in the
Gallery of Maps of the Vatican Museums made between 1580 and 1585.
The population of Sgurgola increased very much in the 18th
century, when the lowlands along the Sacco river were tilled,
and the built-up area extended from the central core around the
castle (Rocca), towards the area of the present main street (Corso
Repubblica) and towards via del Carpino. In 1870 Sgurgola became
part of the Kingdom of Italy.
As Rome became the capital of the Kingdom of Italy, in 1871, a
large number of persons was drawn there from every part of Italy,
and many of them came from Sgurgola, due to its closeness and
to the new railway. Many of the people from Sgurgola worked just
in the State Railways and went and live in the "railwaymen
houses" in the Roman quarter of San Lorenzo, near the railway
station.
As previously said, Sgurgola was the site of social struggles
and antifascist Resistance (see my page on my grandfather Medoro Pallone).
At the end of the First World War, many families of war dead refused
to take part in the official ceremonies in honor of the "fallen",
organizing their own celebrations "because only the proletariat
can participate and feel the pain of mothers and wives who have
been deprived of their loved ones". The families of Giuseppe
Pompi and Antonio Mancini wrote to the Mayor of Sgurgola: "Most
illustrious Sir, we leave your war crosses to the bourgeois government
which would be an offense to other crosses, holier and more sacred,
those that mark the graves of our children, and those that mark
the martyrdom of our hearts . (Federico)
The leaders of the Veterans Association, protected by the carabinieri,
delivered the war crosses on the square of Sgurgola, to the four
or five families who accepted, out of the forty invited. (Federico)
Starting from the fifties of last century, a great development
took place in the area, thanks to the establishment of the Cassa
del Mezzogiorno (a development fund for Southern Italy).
Later on, in the sixties, the Rome-Naples motorway (Autostrada
del Sole) was built. This made many factories rise in the Sacco
valley in the sixties, mainly of pharmaceutical and plastic industries,
where many workers from Sgurgola are still employed, while many
others dwell in the village and work in Rome, thanks to the fast
(even if not frequent and efficient) transports. At the beginning
of third millennium, the construction of the Rome-Naples fast
railroad modified once more the valley.
Beyond the industries in the valley, the Sgurgolan economy is
based on vine and olive trees cultivation: the olives produced
in the village are processed by a local cooperative olive mill.
Moreover domestic size farms breed fowls and rabbits, while in
the valley cattle (mainly dairy breeds) and sheep are reared,
even if the recent events that caused the pollution of Sacco river
and other watercourses seriously damaged the local breeders.
Born
in Sgurgola:
The most illustrious
among the Sgurgolans was Pietro Sterbini,
born in Sgurgola on January 23rd, 1793, physician and revolutionary
fellow of Giuseppe Mazzini. In the Roman Republic of 1849 he was
a member of the Constituent assembly, then Minister of Public
Works. At the downfall of the Republic he had to find shelter
in Switzerland, then in France. With the Italian unification Sterbini
settled in Naples, where he founded the newspaper Roma",
but he passed away in 1863 before he could see Rome becoming Italian
and later the capital of Italy.
Also Attilio Taggi (1867-1950), was an
eminent native and citizen of Sgurgola. he was born in Sgurgola
on September 2nd, 1867, poet in Sgurgola dialect,
in Italian and in Latin, who passed away in 1950.
Luciano Rossi was also born in
Sgurgola on January 20th, 1954. He was the 24 years old
chauffeur of Chief Public Prosecutor of Frosinone, Fedele Calvosa.
He was murdered in Patrica, near Frosinone (15 km, 9 Mi from Sgurgola),
on November 8th, 1978 in a terrorist ambush together
with police officer Giuseppe Pagliei and the same magistrate.
The terrorist group Unità Comuniste Combattenti (Fighting
Communist Units) claimed responsibility for the slaughter.
Visit
You get in the village by the Casilina National Road and then
by the Morolense road (see the itinerary below); a modern bridge,
built close to the old one, maybe of Roman origin, crosses the
river Sacco, which once created a little waterfall,
now replaced by a pumping station.
Beside the bridge an embattled tower of medieval origin can be
seen; its name is Mola Colonna,
and probably it was once a defense for the bridge, but then it
was used as a watermill (mola means "millstone"),
exploiting the Sacco water motive power.
The Mola is 17,5 metres (58 ft) high and it has a square section
with a 7 metres (23 ft) side; it had three floors (just one left),
and of the ancient military purpose it still shows loop-holes
topped by square small windows.
The tower was restored several times in the centuries and for
a short time it was also a power station that provided lighting
for the villages of Sgurgola, Morolo and Supino.
In 2003 the tower was acquired by the municipality and the mayor,
who was the Berlusconi band director (Honi soit qui mal y pense)
placed there the Musical
Bands Museum; the tower is partly still under restoration.
After crossing the river, another bridge crosses the railway (just
before it, on the right side there's a crossroad to Villamagna),
then the road climbs towards the village, and after some bend
(2.5 km, 1.55 Mi about) you get in the village by via della Pietra
Rea (Bad Stone road).
In this road actually, in spite of what the Italian Touring Club
guide maintains, nobody can show you the famous stone on which
the conspirators headed for Anagni for the slap
were harangued.
The roads ends with the square known as "dell'Arringo",
always referring to the events of 1303 (arringa means "harangue"),
but named by the villagers "Muraglione" (the big wall),
by the massive retaining wall that limit it outwards.
On the square a war memorial can also be seen; beside it a wall
fragment with a fresco
(maybe representing Saint Sebastian and other saints) is remnant
of the 13th-century small church of the Arringo,
now destroyed.
The most remarkable thing in the square is the belvedere with
a beautiful view on Sacco valley, on Ernici mountains and, farther,
the Roman Castles.
From Muraglione square
begins the main avenue, the Corso (Corso
della Repubblica), where the "struscio", the traditional
Sunday walk up and down the main road, takes place.
The Corso ends in piazza Pietro
Sterbini (simply known as "la piazza"), where
the mid-18th century parish church of Santa Maria Assunta rises, with
the original wide rectangular portal of limestone monoliths included
in a recently plastered white façade, which replaced the
questionable 1966 brick coat. The three bronze gates of the church
are a work of the Anagni sculptor Pietro Gismondi (1906-2003).
The ancient bell tower
rises apart, on the right hind side of the church (on via 2 giugno),
and rests on a rock block.
Also in piazza Sterbini the massive late 19th
century clock-tower can be
seen; it has three storeys and rests on a wide round
arch, after which on the right side the town
hall rises.
Just beyond the clock-tower arch, on the left, a stairway climbs
to the impressive ruins of the castle (la Rocca), consisting of
the mere base, once topped by a pine, whose outline could be seen
from far away, even from the motorway.
The alleys around the castle are very picturesque: they are narrow,
winding, often with steps, and by their dimensions the quarter
is known as "bùcio pellìccio" that
is "hole of the sieve".
Coming down from the castle
or from piazza Sterbini by via del Carpino (Hornbeam road),
on the left a road goes down to the quarter of San Giovanni (Saint John), where the baroque
church with the same name rises, with its 1888 frescoed ceiling.
In front of the church there is a square
with a small garden and a terrace, even if less panoramic than
the Muraglione.
Coming down again on via del Carpino, after a plain
stretch, the road climbs to the cematary, which is beside
the small church of Santa Maria
in Viano, in ancient enclosed to a Cistercian convent, for
this reason the little church is better known as "la Badia"
(the Abbey) and so is marked on the road signs. Few
remains of the convent are left, that can be seen entering
the cemetery and turning right.
La Badia has very ancient origins, dating back at least to the
eleventh century, and it lodged the daughters of the most important
feudal families of the region, in quality of abbesses or simple
nuns. The convent among the others lodged noble Mary, sister of
Rinaldo da Supino and wife of Francesco Caetani (1260-1317), grandnephew
of Boniface VIII, who apponted him cardinal, with the deacon title
of Santa Maria in Cosmedin. Maria even staying in the nunnery,
give birth to two children of Francesco, a boy and a girl (Waley, quoted by Frale).
According to other
sources Maria had to take a vow of chastity when Francesco was
appointed cardinal. Maria was in Badia on February 28th
1300, when rights on Sgurgola castle were sold by the abbey to
Pietro II Caetani, grandnephew of pope Boniface VIII (and Maria's
brother-in-law). Later on probably Maria married Goffredo da Ceccano,
a participant in Anagni slap together
with her brother Rinaldo.
The church has an asymmetric
hut façade, with a one light window by one side and a mullion
window with two lights on the other; coming in from the large
square you reach a vestibule with a stone
portal, which gives access to the church.
On the lunette that tops the portal lintel, there is a Byzantine
style fresco representing a bust
of Jesus Christ, with the right hand raised to bless and the left
one bearing an open book.
On the slopes of the mountain, few hundreds meters above the village,
the ruins of the thirteenth century small church of San Nicola
(Saint Nicholas), can be seen. The ruins consist of white limestone
walls, in which two floors can be identified; the remains of a
cross vault, a lateral door and, on the main portal, a lunette,
can also be seen.
Beside the small church begins a narrow drift in the mountain,
from which in winter a stream runs down to the village. At present
(April 2014) the church can not be reached being closed for work,
which have for the moment led to the refurbishment of the roof.
From San Nicola you can leave for excursions on the Lepini mounts,
which are full of forests, springs and caves. The small church
probably sheltered the Catalan physician and alchemist Arnaldus
de Villa Nova (1240-1313) who would have shut himself up there
at the end of July 1301 in order to complete his studies that
led him to make a golden astrological seal, held in a leather
girdle, with which he treated Pope Boniface VIII for kidney stones;
it seems his cure was successful, maybe for a mere mechanical
effect on kidneys, yielding to Arnaldus a handsome reward by the
pope and great envy and grudge by papal court. Arnaldus was also
the physician of king James II of Aragon and teacher at Montpellier
University and at Schola Medica Salernitana
(Frale).
Halfway up on the mountain,
southwards to the village, a path reaches San Leonardo hermitage,
at an altitude of 693 metres (2279 ft), raised on the ruins of
a monastery which belonged to the congregation of Santo Spirito
di Maiella, which later was named Celestini congregation, as well
as its founder Pietro da Morrone was made Pope in 1284, with the
name of Celestine the Fifth.
The same congregation owned also the settlements of SantAntonio
Abate in Ferentino and SantAntonio in Supino. The date of
foundation of the hermitage is uncertain, but it is probably very
ancient.
Saint Leonard of Noblat lived in the 6th century and is the patron
saint of Sgurgola since 1200. His statue is usually kept in the
hermitage and on November 6th, on the occasion of the festival
of the patron, it is taken in procession with torches and fireworks
to the parish church of Santa Maria Assunta. After the feast,
which includes also a traditional fair, the statue is taken back
in procession to the hermitage. Near San Leonardo a perennial
spring gushes out, and another source, Fonte dellAcero (Maple
spring), is not far away.
Television
Between 1963 and 1964 the film and TV director Ugo
Gregoretti filmed in Sgurgola, with the participation of local
population and actor Renato Salvatori
a short footage (16'36") for Rai (Italian State Television)
on first national preview in the village of his film "Omicron".
Thanks to Lamberto Corsi, the footage can be seen on You Tube,
in two parts: 1st part 2nd part.
How
to get there
By
train: Rome-Naples line via Cassino -
stop at Sgurgola (68 km/43 mi from Rome). In the station
no tickets can be bought or stamped. The village is 3 km/1.8 mi
far and can be reached by bus (CO.TRA.L. or Corsi & Pampanelli);
the bus ticket can be bought at the newsagent over the railroad
bridge (300 metres, 350 yds from the station). If you need to
reach the station from the village you can get the tickets at
the tobacconist in corso Repubblica.
By
car: Rome-Naples Motorway (A2) at 12
km/7.5 mi from the village. Go out at Anagni-Fiuggi station, after
the tollgate turn right (direction: Anagni) and after 100 mt.
(110 yds) turn right at the slope for Frosinone (National Road
SS n.6, Casilina); after about 4 km/3.5 mi, just passed a small
village (Osteria della Fontana), turn right for Sgurgola (Via
Morolense. Beware: the turn is just after a hump and a bend).
Now keep on the main road until next fork: don't turn left to
Morolo, but keep ahead to Sgurgola (follow the signs). Go down
the slope, under the fast railroad, cross a bridge on a waterfall,
beside an ancient tower, and another on the railroad, then, at
the next fork, stride on, up the slope; the road climbs for about
3 km/2 mi, and after several bends you get in the village.
Instead of the motorway you can take the via Casilina (National
Road SS n.6) from Rome, and as you reach Osteria della Fontana
just follow the indications given above for the motorway route.
