Koufonisia is a former community in the Cyclades, Greece. Since the 2011 local government reform it is part of the municipality Naxos and Lesser Cyclades, of which it is a municipal unit. Koufonisia consists of three main islands, Kato (Lower) and Pano (Upper) Koufonisi, and Keros, that belong to the complex of Small East Cyclades. Geographically, it is located on the southeast side of Naxos and on the west side of Amorgos. Uninhabited Keros is a protected archaeological site from which a large number of ancient Cycladic art pieces have been excavated in the 20th century. Their name comes from the numerous caves the waves have shaped along their shores, which, when seen by pirates, gave them the impression that the islands (in Greek “nissia”) were hollow (in Greek “koufio”) – therefore Koufionissia and later Koufoníssia. Koufonìsia islands are a beloved destination for those seeking to enjoy the original laid-back Greek lifestyle: peaceful and relaxed atmosphere, sun-drenched beaches with azure waters and…plenty of tavérnas with fresh fish!
