The highest point is Profitis Ilias, 269 meters above sea level. Patmos' main communities are Chora and Skala, the only commercial port. Other setllements are Grikou and Kampos. The churches and communities on Patmos are of the Eastern Orthodox tradition. In the summer of 2006,Historic Centre (Chora) with the Monastery of Saint John "The Theologian" and the Cave of the Apocalypse,were declared by Unesco as World's Heritage sites. Patmos is most notable for its mention in the Christian scriptural Book of Revelation. The book's introduction states that the author, John, has been exiled to Patmos, and that there he saw and recorded a vision from Jesus. Very early Christian tradition identifies this John as Saint John the Evangelist. As such, Patmos is a destination for Christian pilgrimage. Visitors can visit the cave where John supposedly saw the Revelation. Several monasteries on the island are dedicated to Saint John. Patmos is also home to the Patmian School, a notable Greek seminary. The island is also the place where the Nation of Islam claims that the black scientist Yakub created the white race as part of a misguided breeding program.
