Kos is rich in history, offering visitors a journey back in time. Start with the Asclepieion, an ancient healing temple dedicated to the god Asclepius. Walk through the Ancient Agora, where the ruins of temples, markets and mosaics reveal the island's vibrant past. The Knights' Castle stands as a reminder of medieval times, while Hippocrates' Platanos is a living tribute to the 'Father of Medicine'. Don't miss the Roman Odeon, a beautifully preserved theatre.
