Monastery of St. John

The Monastery of St. John the Divine (Agios Ioannis o Theologos), also known as the Monastery of St. John the Theologian, is a fortified Orthodox monastery on the island of Patmos in Greece.

In 1088, the Byzantine Emperor Alexios Komnenos gave the island of Patmos to the soldier-priest Ionnis Khristodhoulos "the Blessed." The greater part of the monastery was completed by Khristodhoulos in just three years. Its heavily fortified exterior was necessitated by the threats of piracy and Seljuk Turks.

The monastery consists of interconnecting courtyards, chapels, stairways, arcades, galleries and roof terraces. Hidden in the walls are fragments of an ancient temple of Artemis that was destroyed in the 11th century. The main chapel is lovely, as is the adjoining Chapel of the Theotokos, whose frescoes date from the 12th century.

The Treasury has an impressive array of religious art and treasure, mainly consisting of icons of the Cretan school. The star exhibits are an unusual mosaic icon of Agios Nikolaos and the 11th-century parchment granting the island to Khristodhoulos.

About halfway up (or down) the cobbled path that leads here is the Cave of the Apocalypse, the very place where St. John is believed to have received his revelations.
