History

From Bronze Age Settlements to Modern Greece

The history of Kos stretches back to the first Primaeval Bronze Age (2900 - 2100 BC), with archaeological finds indicating early inhabitants. The island was initially colonized by the Carians, and later, in the 11th century BC, the Dorians arrived, bringing with them the Asclepius cult and establishing sanatoria that brought renown to Kos. During the 7th and 6th centuries BC, Kos became a member of the Doric Hexapolis, flourishing with the establishment of seven townships.

In the 5th century BCE, Kos became the birthplace of Hippocrates, the celebrated physician who founded a school of medicine on the island. This period marked significant political and cultural flourishing, with Kos becoming known for its wine exports and its own coinage. After a period under Persian and Athenian control, Kos regained independence and established a democratic government in the Hellenistic era, becoming an ally of the Ptolemy dynasty. The island's strategic location on trade routes between Egypt, Syria, Cyprus, and Anatolia contributed to its prosperity.

Kos generally maintained a friendly relationship with the Romans, becoming a free city in 53 AD. Following the fall of the Roman Empire, it came under Byzantine rule, though it faced constant pirate raids. In 1315, the island was sold to the Knights Hospitaller of Rhodes (Knights of St. John), who constructed impressive fortifications like the Castle of Neratzia. The Knights held control until 1523, when the Ottoman Empire took over for 400 years. In 1912, Italy occupied Kos, undertaking infrastructure projects and archaeological excavations. During World War II, the island was occupied by Italian and then German troops, before becoming a British protectorate and finally being ceded to Greece in 1947. Today, the modern city of Kos is built upon the ancient town, creating a unique atmosphere where Venetian mansions, traditional houses, and archaeological monuments coexist.

What to see

Kos Town is a dynamic center with a mix of Venetian and Ottoman architecture and numerous historical sites. The Archaeological Museum in Eleftherias Square offers a good starting point for a cultural tour. Nearby, the Ancient Agora, dating to the 5th century BC, was the administrative and commercial center of antiquity, revealing mosaics, temples, and statues. You can see remains of temples dedicated to Aphrodite and Hercules within the Agora.

Adjacent to the Ancient Agora stands the Plane Tree of Hippocrates, a symbolic tree believed to be a descendant of the one under which Hippocrates taught. The imposing Castle of the Knights (Neratzia Castle) guards the harbor, offering a glimpse into medieval grandeur. Other notable sites include the Roman Odeon, a well-preserved amphitheater, and Casa Romana, a reconstructed Roman villa with impressive mosaics. Just outside Kos Town, the Asklepion, an ancient healing center sacred to the god Asclepius, rests on a hill with expansive views.

Beyond the town, consider a trip to Zia, a mountain village known for its sunset views. For a taste of traditional Greek fishing village life, Mastichari offers fresh fish and a relaxed atmosphere. The island also offers beautiful shores like Paradise Beach, Tigaki Beach, and Mastichari Beach, as well as the unique Therma Beach with its natural hot springs.

When to visit

The best time to visit Kos is between May and October, when temperatures are comfortable, rainfall is low, and conditions are ideal for exploration. June and September are often considered the sweet spots, offering a balance of pleasant weather, warm sea temperatures, and fewer crowds than the peak summer months of July and August. For those prioritizing history and culture, April and October provide mild temperatures and a quieter atmosphere.

Practical

Kos is accessible by direct flights from many European cities, or by ferry from mainland Greece and other Greek islands. The island has a reliable and affordable public bus network connecting major towns and beaches. However, renting a car, scooter, quad, or e-bike offers greater flexibility to explore remote shores and mountain villages at your own pace. Cycling is particularly popular, with dedicated paths along the northern coast.

While credit cards are widely accepted, it's advisable to carry some cash for smaller tavernas, local shops, and attractions with lower entrance fees. Tipping is not mandatory but is appreciated. Accommodation options range from luxurious hotels in Kos Town to family-run apartments and budget-friendly stays across the island.
