Dating from the 18th century, it’s built on an all-green slope and is a unique example of insular monastery architecture. It took its name from the only spring of the island, which, according to tradition, is known for its healing powers. The temple is a domed Basilica, and its interior impresses with its marvelous woodcut iconostasis (templon) carved in Cappadocia of Asia Minor in the 17th century.
