Peristerona

The castle at Peristerona, known locally as Kales, is a Byzantine-era ruin perched on a low hill above the southwestern shore of Lake Volvi. Its history is almost entirely obscure. Scholars cautiously describe it as a fortified settlement, probably Byzantine, but no medieval source names it. The region remained a Byzantine province until the Ottoman conquest of 1383, aside from interludes of Latin rule (1204-1221/4) and Serbian annexation (1345-1371), yet the castle goes unmentioned throughout. It might be the Volvon fortress noted by Procopius, though that name is usually assigned to a castle in the lake itself. The masonry, semi-processed stones set in lime mortar with occasional tile fragments, confirms a Byzantine date without narrowing it further.

The fortification encloses roughly 300-350 metres, with the best-preserved section on the vulnerable southern side: a stretch of wall five to six metres long, three metres high and 1.3 metres thick. A collapsed tower is suggested by stone piles nearby. West walls survive to a modest height, while the northern slopes, descending to the lake, are overgrown, with one detached wall corner tumbled downhill. A probable gate opening survives in the northeast. Southeast of the castle lies a larger enclosed settlement of about 900 metres perimeter, with traces of a paved road, possibly a route of the Egnatia Odos.
