United States or Australia. In June 2008, Anastassios Aliferis, the Socialist mayor of the island performed the first same-sex marriages in Greece, citing a legal loophole and defying claims of illegality by a Greek prosecutor. In late 2018 Tilos will become the first island in the Mediterranean to run exclusively on wind and solar power. Geography Tílos has an inverted 'S' shape, is about long, north-west to south-east, with a maximum width of and an area of about . The island has a mountainous limestone interior, volcanic lowlands, pumice beds and red lava sand, like its north western neighbour Nisyros. It is well supplied by springs, and is potentially very fertile and productive. Its coasts are generally rocky or pebbled, but there are also a number of sandy beaches. Landmarks At the north-west end of the island, the Monastery of Áyios Pandeleímon, (also the island's patron saint), sits on the slopes of Mount Profítis Ilías (654 m). The monastery features fresh cold water springs as well as an enormous loquat tree (called Musmulla in Greek). The mountain borders a fertile plain running across the island's width, with the settlements of Áyios Andónis to the north and Éristos to the south. To the north-east of the plain is the island's capital, Megálo Chorió, built in the early 19th century at the foot of the ancient city of Telos. The archaic ruins stretch up to the site of the acropolis of the ancient city, dedicated to Pythios Apollo and Poliada Athina, and the Venetian Kástro, built over it. To the west is Kharkhadió Cave, where excavations in 1971 unearthed Neolithic finds and bones of dwarf elephant. Above the cave stand the ruins of the medieval Fortress of Mesariá. At southern end of the island, bordered by more fertile meadows, is Livádhia, the major harbour and economic centre of the island. The island's old capital, Mikró Chorió, first settled in the 15th century by the Knights of the Order of St John, overlooks the bay. It has been completely abandoned since 1960, its inhabitants having moved down to the harbour in the 1930s. A number of other settlements such as Lethrá, Gherá, and Panó Méri have similarly been abandoned. Mount Áyios Nikoláos (367 m) stands to the south of the bay. Castles Kástros (castles) have protected the island's inhabitants from pirate raids since the Dark Ages. Megálo Chorió Mesariá Mikró Chorió Agrosikiá Stavroú
