Serifos is an Aegean island of the northwestern Cyclades, inhabited by about 1500 locals, 75 km² in size and almost circular in shape (9 km wide and 10 km long). Its aspect is barren, wild and inaccessible, with a rocky relief.

A long mountain massif of granite and gneiss extends across the island, reaching its highest point at 582 meters above sea-level in a peak named Troulos. On the western side, the land descends more steeply to the sea than on the eastern side, where a monadnock (an isolated mountain), located halfway down the slope, is dotted with the snow-white cubic houses of the attractive Hora (called Serifos in most maps), which offers panoramic views of the wide Livadi Bay.

Tourism is centered on the port of Livadi, which is still a quiet place except in August. The island has retained its original character, especially in the north, where the landscape is dominated by idyllic farming villages and terraced fields.

From the time of the ancient greeks onwards and especially from 1870 up to 1963, iron ore was mined in the south-west of the island, as numerous remains testify
