Greece - Historic Centre (Chorá) with the Monastery of Saint John "the Theologian" and the Cave of the Apocalypse on the Island of Pátmos

"The small island of Pátmos in the Dodecanese is reputed to be where St John the Theologian wrote both his Gospel and the Apocalypse. A monastery dedicated to the ‘beloved disciple’ was founded there in the late 10th century and it has been a place of pilgrimage and Greek Orthodox learning ever since. The fine monastic complex dominates the island. The old settlement of Chorá, associated with it, contains many religious and secular buildings."
