The island of Koufonissi or Koufonision in Greece

Previously the island was called Lefki, meaning "white", due to the white sand and the predominantly white cliffs of sandstone that dominate the landscape of Koufonissi. It was an important port and a place where people dived fore sponges and shells. From these shells a valuable purple dye was extracted. It is likely that the island also played an important role in the Minoan economy. The City states of Itanos and Ierapytna (the old Ierapetra) continually fought for the ownership of the island. This can be seen on plaques that have been excavated in Minoan Kato Zakros and in Asia Minor. One of these plaques is immured in the wall of the monastery church of Toplou. In 132 BC the island came into the hands of Itanos.

Excavations on the island have exposed buildings dating from the Minoan, Hellenistic and Roman times, but there are also caves that were used as a church during the Byzantine times and later during the Turkish domination by Christians. Because so many buildings have been uncovered from ancient times the island is also called "small Delos" (after the island of Delos near Mykonos in the Cyclades). The main building that has been found is a theatre that could house up to 1000 people. Also a temple, pieces of marble from a colossal statue, a villa with eight rooms and several cottages, probably where the fishermen lived, have been found. Pottery, coins, needles and fishing equipment have been dug up. There are also the remains of a lighthouse that was bombed by the Germans in the Second World War.
