Patmos is the northernmost island of the Dodecanese complex. It is situated northwest of Leros and southeast of Samos.
In 1999 Patmos was declared a World Heritage Site by UNESCO.
The island covers an area of 34km2 and the length of its coastline is 63km.
It consists of three parts that are connected to each other by two isthmuses near the middle and the southern end of the island.
Patmos is an island of volcanic origin and rocky landscape. Its highest peak is Profitis Elias (270m).
Its terrain consists of high and steep hills that alternate harmoniously with lower grounds.
The coastline of Patmos is full of gulfs, coves and capes.
The climate is mild in the wintertime and cool in the summertime. What makes its climate special is the extraordinary clarity of the atmosphere and the constant sunshine. In Patmos only a small amount of rainfall is observed, which in combination with the lack of natural springs, has always been a problem for the residents.
The two largest settlements are Skala, the island’s harbor, and the beautiful Chora, where the castle with the monastery of Saint John the Theologian (Agios Ioannis o Theologos) stands. Other settlements are Grikos and Kampos.
