Deserted in the early 19th c., possibly during an epidemic, the medieval settlement of Palio Pyli on the hillside of Mt Dikeos is a world away from the hustle and bustle of the island’s seaside resorts. Among its ruins, you can explore the Byzantine churches of Panaghia Kastriani, Aghios Antonios and Taxiarches – all three with some lovely murals and with ancient architectural elements.
