Imerovigli has many lovely churches, all made in the Cycladic architectural style. They most notable are the church of Ai-Stratis, in the centre of the village, and the Monastery of Saint Nikolaos, on the way connecting Imerovigli to Fira. Another famous site of Imerovigli is Skaros, which are the remains of a Venetian Castle built in 1207 by Marco Sanudo, the ruler of all Cyclades islands that time.
