The Roman Odeon of Kos in the Dodecanese region is a fantastic historical site that dates back to the 2nd and 3rd centuries. The Romans built this odeon and other notable constructions, including the Gymnasium and the Roman baths. All these structures are situated east and west of the Casa Romana, a part of the Ancient Town, and several excavation areas surround them.
Next to the ancient Agora of Kos, opposite the fortress of Neratzia, is where you will find one of the oldest trees in Kos: the plane tree of Hippocrates. This historical tree is visited by thousands of people every year due to a story that became a legend.
