Kalavryta Castle

The Castle of Kalavryta, also called Oria, crowns a rocky spur of Helmos about 1.5 kilometres east of the town, at roughly 1,170 metres. It was raised in the 1210s by Othon de Tournay, first Frankish baron of Kalavryta, after the Fourth Crusade carved up Byzantium and the Principality of Achaea distributed the Peloponnese among its knights. The castle slipped from Frankish hands in the 1260s, seized by Byzantine raiders rather than treaty, and for decades stood as an isolated Greek outpost; the Franks answered by building Tremoulas Castle on a higher neighbouring peak. Theodore Palaiologos sold it to the Knights of St John in 1400, but they held it only until 1404. It endured a grim end under Mehmed II in 1460, whose garrison commander Doxa was flayed alive. Venetian rule followed from 1686 to 1715, then Ottoman until 1821. Today only scattered ruins survive: a metre-thick lime mortar wall, traces of ramparts, cisterns, two half-collapsed towers, and the eastern side of the main gate. Fifty houses once stood within; a few foundations remain. The site may be ancient Kyneitha’s acropolis, and old masonry was reused in its build.
