Trizonia

On the islet of Trizonia, a small community of 64 people in the Corinthian Gulf, a low hill called Palaiokastro, meaning old castle, carries the remnants of a medieval fortification. The site, about 1,500 metres from the port on the north-west side, is easily reached. What survives is a dry-stone enclosure and the traces of a tower, both now in ruins. The original construction date is unknown, though the style points most probably to the Byzantine period. Some of the newer buildings on the islet appear to have been raised using stone quarried from the old walls, which may explain why the tower itself is no longer visible. The fortification is not substantial, and its modest scale suggests a local refuge rather than a grand defensive work. For the visitor, Palaiokastro offers a quiet, unassuming glimpse of medieval life on a small island, where later habitation has recycled the past into the present.
