It was once called "Hierà" (the sacred), but also known as "Termessa" or "Terrasia".
Today, it is famous for its thermal baths fed by underwater springs.
This island of 21 km² and 500 meters in altitude is the closest to the Sicilian coast.
Its name clearly describes its geography: a land of lava and fumaroles, yellow sulfur on the rocks, and black sands.
There are three volcanoes on the island: the first, extinct since prehistoric times; the second is Vulcanello (123 m), inactive since 183 B.C.; the third is Fossa di Vulcano, where only fumaroles remain active.
