Monastery of St John the Theologian

Top choice

As this immense 11th-century monastery-cum-fortress remains active, only a small portion is open to visitors. The entrance courtyard leads to a sumptuously frescoed chapel, fronted by marble columns taken from an ancient temple. Don’t expect to attend a service; daily worship is at 3am! The museum of church treasures upstairs displays the original edict establishing the monastery, signed by the Byzantine emperor in 1088.
