Where is Kos Located?

Kos lies in the southeastern part of the Aegean Sea, just 4 kilometers (2.5 miles) off the coast of Bodrum, Turkey. It is part of the Dodecanese island chain, situated between Kalymnos to the north and Nisyros to the south. The island spans approximately 290 square kilometers (112 square miles) and has a population of around 33,000 people. Its capital and main port, also called Kos Town, is a hub for ferries and flights.
A Brief History of Kos
Kos has a long and fascinating history, shaped by various civilizations over the centuries:
– Ancient Times: Inhabited since the Neolithic period, Kos flourished during the Classical and Hellenistic eras. It was a center of learning and medicine, home to the famous physician Hippocrates (460–370 BC), who founded the Asklepieion, an ancient healing temple.
– Roman & Byzantine Rule: The Romans took control in the 2nd century BC, followed by the Byzantines, who fortified the island against Arab invasions.
– Knights of St. John: In the 14th century, the Knights Hospitaller ruled Kos, constructing strong fortifications, including the Castle of Neratzia in Kos Town.
– Ottoman Era: The Ottomans occupied Kos from 1523 until 1912, leaving behind mosques and Turkish baths.
– Italian Occupation: After the Ottomans, Italy took control until 1947, when Kos finally became part of Greece.
Today, the island’s layered history is visible in its archaeological sites, medieval castles, and Ottoman architecture.
