"The Jerusalem of the Aegean" is one way of describing Patmos or Patnos, as it was referred to in one 5th century inscription. It was here that St. John the Theologian was exiled between 95 and 97 A.D. and was inspired to write the Book of Revelation or Apocalypse.

Patmos, situated between Leros and Ikaria, is a mountainous island with rocky soil and an abundance of small coves.

The majestic fortress-monastery crowns the hill above the port, surrounded by dazzling white houses, miniscule churches and grand sea captains' mansions, separated from each other by narrow lanes, high walls and small squares.
