Hippocrates Plane Tree

Standing in the heart of Kos Town, the Hippocrates Plane Tree is said to be one of the oldest trees in Europe, where the father of modern medicine himself once taught his students. It's a genuinely humbling spot — you're looking at a living landmark tied to the origins of medical science, framed by the Castle of Knights and the Gazi Hassan Mosque right next door. The tree's massive, gnarled trunk is held up by ancient marble supports, making it feel as monumental as the history surrounding it.
