During the Minoan period the island was used as a worship area. Later in the 15th century the venetians built a fortress to protect the area from invaders. The name 'Thodorou' was given to the island from the small church of St. Thodoros which is on the island.
Today the island is a national park and an area of special protection as a refuge for the Cretan goat known as KRI-KRI, which is an endangered species. About 60 of them live on the island today, along with other wild animals, among which there are mammals, birds of passage and sea birds.
