A small Greek island KOs is one of the most visited Islands of the Dodecanese (Southern Sporades). Its scenic natural landscapes, rich in ancient history and an abundance of historical and cultural monuments attracts huge number of tourists.

One of the most interesting sights of the island of KOs is considered an excellent Archaeological Museum, located in the eponymous capital on eleftheria square. The Museum is housed in a well-preserved two-storey neoclassical building which was built during the reign of Spit on the Italians in 1935.

In the Museum's collection are largely artifacts found during archeological excavations on the Islands of KOs and Rhodes. There are also findings from other Islands of the Dodecanese. The Museum covers a fairly reasonable period of time, beginning with the prehistoric period, but especially valuable are the exhibits of the Hellenistic and Roman eras.

The Museum presents various ceramics and metal, sculpture, statues, funerary artifacts, coins, magnificent mosaics, architectural fragments, and more. Of particular interest among the Museum exhibits a superb collection of antique statues, among which the most valuable are the statues of Alexander the great, Asclepius, Hippocrates, Dionysus, Hermes, Demeter, Gigai and Artemis. The floor of the atrium is decorated with magnificent mosaics depicting scenes of the arrival of Asclepius on the island of KOs (3rd century BC).

Unfortunately, the area of the Museum was too small to hold all the exhibits at the same time, so a significant portion of historical relics stored in the Museum funds. However, the most interesting and important exhibits in the permanent exhibition.

Archaeological Museum regularly conducts educational programs for pupils and students.
