Kalyvia

The few surviving stones of this late Byzantine castle sit on a low rise at a spot called Melissa or Paliokastro, in the Maria valley on Thassos, just north of Kalyvia, itself a suburb of Limenaria. The origin is probably 13th or 14th century, though little else is certain. What remains is scant: a handful of ruined walls, enough to mark the site but not to reconstruct its plan or purpose. The castle would have watched over the valley below, a modest defensive work of the island’s late medieval period, when Byzantine authority was fraying and coastal watchposts mattered. Today the place is quiet, the masonry half-buried in scrub, and the visitor must conjure the tower or enclosure from the rubble. It is a site for those who enjoy the archaeology of hints rather than grand statements, and the name Paliokastro, old castle, is about as much as the ground confirms.
