Mysterious megalithic stone structures scattered across Mount Ochi, built from massive slabs without mortar. Their purpose remains debated, adding to their allure.
A small Venetian-era tower, the town’s most recognisable landmark. It dates to the 13th century and once formed part of Karystos’ coastal defences.
A powerful 13th-century Frankish fortress built by Ravano dalle Carceri. Despite its name, it is constructed from grey-yellow stone and occupies a naturally defensive site with dramatic views over the bay. Substantial ruins of the inner enclosure, walls, and later additions still survive.
A small but worthwhile museum with finds from southern Evia, including classical and Roman artefacts.
