The warm, graceful charm and sedate pace of Kos Town is experienced at its best in this lovely cobblestone square, immediately south of the castle. Sitting in a cafe here, you can pay your respects to the Hippocrates Plane Tree . Hippocrates himself is said to have taught his pupils in its shade. The ancient sarcophagus beneath it was converted into a fountain by the Ottomans, while the 18th-century Mosque of Gazi Hassan Pasha , now sadly boarded up, stands opposite.
