Kos | Greece

Kos is the third-largest island of the Dodecanese, located in the southeastern Aegean Sea near the coast of Turkey. It is defined by its flat topography, extensive sandy coastlines, and its historical legacy as the birthplace of Hippocrates, the father of modern medicine.

Historical Timeline

Classical Antiquity: Emerged as a major center of healing and culture. The Asklepieion of Kos was one of the most famous sanatoriums of the ancient world.

Knights Hospitaller (1315–1522): The island was ruled by the Knights of St. John, who built the massive Neratzia Castle to guard the harbor against Ottoman expansion.

Ottoman & Italian Rule: Following four centuries of Ottoman rule, the island was occupied by Italy in 1912. The Italians implemented a grand urban plan for Kos Town, introducing wide boulevards and rationalist architecture.

Unification: Kos was officially incorporated into the Greek state in 1948 along with the rest of the Dodecanese.
