The beautiful island of Kos, the birthplace of Hippocrates, the Father of Medicine.  The island’s most important ancient site is the Asklipieion, built on a pine-covered hill 3km southwest of Kos Town. The Asklipieion consisted of a religious sanctuary devoted to Asclepius (the god of healing), a healing center, and a school of medicine, where training followed the teachings of Hippocrates. The island’s trademark is its medieval castle of the Knights situated at the entrance of the port. Stroll around famous squares like Platánou Square and Elefthería Square and admire the Antik buildings, remains of the Italian rule. Pay your respects to the plane tree where Hippocrates himself, the Father of Medicine, used to teach his students. It is considered to be 2500 years old and the oldest in Europe.
