There are an unexpected ten chapels associated with the Monastery of Saint John the Theologian. Three are outside the walls. Of the seven inside, three are most noteworthy. The Katholikon (main church) is the oldest from the late 11th century. You will be impressed by the 17th century paintings of St. John’s miracles and the large wooden iconostasis. Inside the Chapel of Holy Christodoulos is the tomb of the founder, the skull of St. Thomas and pieces of the True Cross. Equally impressive are the 12th century paintings inside the Chapel of the Virgin Mary (also called Theotokos). Pictured is the Chapel of the Holy Cross, built in 1598.
