Rogoi

Rogoi (Ῥογοί or Ῥωγοί) is a Byzantine castle in Nea Kerasounta near Preveza, in western Greece. It is located on the site of the ancient city of Bouchetion (Βουχέτιον), which was abandoned in the late 1st century BC. Re-occupied in the 9th century, it became a bishopric and was refortified, playing an important role in the region's history in the 14th and early 15th centuries. It was abandoned again after the Ottoman conquest in 1449.

Location
The castle is located some 4.5 km southwest of the village of Nea Kerasounta, on a 29 m tall hill on the northern bank of the Louros river, which surrounds the base of the hill on the eastern, southern and western sides. The castle was built on the location of the acropolis of the ancient city of Bouchetion. Despite its inland location today, in Antiquity the hill seems to have been an island, and literary references confirm that Rogoi remained a coastal location in the Middle Ages as well, with the Ambracian Gulf extending further to the northwest than it does today.

History
The site was identified by 19th-century scholars with ancient Charadrus, until N. G. L. Hammond established its modern identification with the ancient city of Bouchetion. Bouchetion was an Elean colony founded in the 7th century BC, and served as the port for the inland settlements of Elatria (at the modern village of Palaioroforos, 10 km west of Rogoi) and Baties (modern Kastro Rizovouni, some 7 km to the north of Rogoi). In the 4th century, Bouchetion was incorporated into the unified kingdom of Epirus by the Molossian king Alexander I (r. 350–331 BC). The town followed the fortunes of the Epirote state. In 167 BC, it was sacked during the Third Macedonian War. Although its strategic location ensured that the site remained occupied thereafter, it was eventually abandoned after the foundation of Nicopolis in 28 BC.

The name "Rogoi" derives from a Sicilian Greek term for "granaries", and may indicate its foundation in middle Byzantine times (ca. 9th century) by Sicilian settlers. From the 9th century, Rogoi was also the seat of a bishopric, a suffragan of the Metropolis of Naupaktos. In the period between ca. 1000 and ca. 1500, the local inhabitants changed the course of the Louros river to its present form, aiming to drain its marshes and increase the available farmland, and possibly to enhance the protection of the castle itself, which was now surrounded on three sides by the river.

The medieval settlement appears in historical sources chiefly in the 14th–15th centuries, when it played a role in the wars of various local potentates for control over Epirus. Thus it was attacked without success by Charles II of Naples in 1304, when Anna Palaiologina Kantakouzene, the regent of the Despotate of Epirus, refused to acknowledge Angevin suzerainty. In 1339, the castle of Rogoi, along with the Epirote capital, Arta, and the fortress of Riniasa or Thomokastron, was seized by Epirote rebels who rose up against the annexation of Epirus into the Byzantine Empire in the previous year. Emperor Andronikos III Palaiologos and his Grand Domestic, John Kantakouzenos, blockaded Rogoi, which was eventually persuaded to surrender by Kantakouzenos. In the 1340s, Epirus fell into the hands of the Serbian Empire during the Byzantine civil war of 1341–47, but Serbian rule was soon challenged by the attacks of Albanian tribes, and by the 1360s Rogoi and Arta were in the hands of the Albanian chieftain Peter Losha. After Losha's death in 1374, his domain was taken over by the fellow Albanian ruler of Acheloos, Gjin Bua Spata. The town remained in the hands of the Spata family until 1416, when the last Albanian ruler, Yaqub Spata, was defeated by the Count palatine of Cephalonia and Zakynthos, Carlo I Tocco, who in 1411 had become master of Ioannina. Carlo and his brother, Leonardo II Tocco, took possession of Arta and Rogoi, thereby restoring the Despotate of Epirus to its traditional boundaries. Rogoi was finally abandoned after the Ottoman conquest of the region in 1449.

Ciriaco de' Pizzicolli visited the castle in the early 15th century, and recorded that the relics of Saint Luke were kept in a church there; according to contemporary Serbian texts, these had been moved there from Constantinople after the fall of the city to the Fourth Crusade.

Castle
For the first two centuries of its existence, Bouchetion was apparently unfortified, and the first fortification on the site consisted of a simple circuit wall of 450 m length enclosing the flat space on the top of the hill. This was later enlarged by an irregular wall enclosing the entire northern slope of the hill, increasing the length of the outer walls to 730 m and doubling the enclosed area from 9,000 to 18,000 m2. Still later the walls were again expanded to include the northeastern part of the settlement, so that in its final extent the ancient fortifications formed an outer circuit of 1,000 m and encompassed an area of 37,000 m2.

The medieval castle extant today was built on the remains of the first two phases of the ancient acropolis, and follows the course of the ancient fortifications, incorporating their foundations. The medieval outer circuit wall was largely built on the traces of the ancient walls, with the different styles of masonry making the two structures clearly discernible from each other. To these were added internal transverse walls, reinforced by towers, dividing the enclosed space into three baileys. The outer bailey also contained a monastery, of which only the 15th-century church of the Assumption remains. The castle's interior is now mostly ruined and overgrown with vegetation. The date of the Byzantine re-fortification is uncertain, possibly from as early as the site's re-occupation in the 9th century to the 13th/14th centuries.

The site has not yet been excavated, except for maintenance work on the walls undertaken in the 1978–80 period.
