Patmos is a small island measuring around 12 kilometres in length in the Dodecanese Islands not far from Turkey and is called the "Jerusalem of the Aegean". This is because the island is home to many beautiful monasteries as well as the cave where St. John the Apostle wrote his "Apocalypse". The port of Skala, the capital of the island, can be reached by sea via a long, narrow inlet. The city lies in the shadow of the medieval castle-convent of St. John. It can be seen from all directions from sea and many pilgrims travel here each year. A visit to the village of Chora with its narrow streets is also a must. Some of the taverns provide a breathtaking view right down to Skala. Other sights include: the monastery of St. Christodoulos, the holy cave of the revelation and Agia Anni chapel.
