The Byzantine fortress of Monte Kassar, seventh to ninth century

Overview

Castronovo lies inland among the Sicanian mountains, in the highland corridor between the Palermo hinterland and the centre of the island. Three things in its territory get called the castle at one time or another, and it is worth separating them: the great Byzantine fortification on Monte Kassar; the medieval castle in the town, of which the surviving towers are now part of the Chiesa Madre; and the ruins on the rock of San Vitale above.

The archive entry and the Comune place the castle on different ground. The Cultural Heritage Online entry says the fortress stood at the foot of Monte Kassar until the Byzantine age and was afterwards rebuilt on the hill of San Vitale, at 750 metres, where its vestiges can still be seen. The Comune di Castronovo di Sicilia says the castle stood on the wide natural platform at the foot of Monte Kassar, surrounded by a broad ditch now entirely filled in. Both are recorded here; the contradiction is real and is not resolved by choosing.

History

Byzantine rule ended with the Muslim conquest of 839–840. The castle in the town was built in 1077 by Count Roger, close to an earlier castle with which, tradition has it, it communicated by an underground passage; the Normans are recorded as raising two castles here and a chapel dedicated to Saint George. It served as a military post on the road between the ancient cities of Himera and Akragas.

Towards the end of the thirteenth century the lord of Castronovo was the Genoese Corrado I Doria, admiral of Sicily, and the town stayed with his line until 1370. In 1302 the castle became the headquarters of Frederick III of Aragon, who opened here the negotiations that led to the Peace of Caltabellotta with Charles of Valois, captain general for Charles II of Anjou. In 1375 Manfredi III Chiaromonte became count of Castronovo and enlarged the castle; in 1391 the barons swore their oath here against Martin the Younger of the counts of Luna, who took the throne of Sicily in July of that year.

In 1411 the castle, then the property of baron Matteo Moncada, gave refuge to Bianca of Navarre, queen of Sicily and daughter of King Charles III of Navarre. In 1423 Moncada was succeeded by his son Guglielmo Raimondo, who restructured the building. In the seventeenth century it became a prison — recent excavation turned up the coins a prisoner had hidden in a cell — and the settlement drifted down off San Vitale to lower ground, leaving the height to be abandoned.

What you see

Not much, and not what earlier English versions of this entry described. Of the old castle a few readable ruins remain. The complex ran on an irregular plan and included a cylindrical tower and a vaulted cistern cut into the rock. The walls are thin for a fortress, about a metre, built of limestone blocks of varying size packed with tile fragments and bound with mortar. The entrance was on the south side, almost certainly over a drawbridge. Among the ruins stand the remains of the Chiesa del Giudice Giusto, a small Norman church with frescoes in the apses.

Two of the castle’s towers survive because they were built into the parish church, the Chiesa Madre della Santissima Trinità: one became the bell tower, the other the present apse. That is the most substantial standing piece of the castle, and it is inside a church rather than on a hilltop.

Above the town, Monte Kassar carries a Byzantine fortress of the seventh and eighth centuries that is among the largest known in the island: defended on three sides by sheer rock and on the fourth by a wall three metres thick and two kilometres long, enclosing some ninety hectares. Excavation and survey there — the east gate, a soldier’s house, small barracks, a later church — have run in campaigns from 2005 through 2014–2019, alongside work on the settlement of Casale San Pietro.

Cultural significance

The interest of Castronovo is the sequence, not any single monument: a Byzantine command post of the seventh century on the mountain, an Arab and then a Norman castle below it, a Chiaromonte county, an Aragonese king negotiating a peace treaty in its hall, a queen in hiding, and finally a prison. Recent archaeology has made this one of the better-studied inland sequences in Sicily, published as Castronovo di Sicilia. Ricerche di storia e archeologia 2014–2021.

A caution on a claim that has circulated: Castronovo is not part of the UNESCO world heritage site «Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale». Its Arab-Norman fabric is real; the listing is not.

Practical information

• The ruins are in the open above the Rione Batia and are reached on foot from the town; ask at the Comune about current conditions of access, which are not formally managed.
• The Chiesa Madre della Santissima Trinità, which incorporates the two towers, is in Via Duomo and is open for worship.
• Monte Kassar is an archaeological area on the mountain above; it is a walk, not a stop, and is best approached with local guidance.

Getting there

Castronovo di Sicilia is reached by car from the A19 Palermo–Catania, leaving at Tremonzelli and continuing south on the SS189. The nearest railway station is Lercara Friddi, about 12 kilometres to the north-west; coaches on the Palermo–Agrigento route also serve the town.
