Neratzia Castle
Κάστρο της Νερατζιάς
A harbour fortress built by the Knights Hospitaller in the 15th century, with double walls guarding Kos harbour. From the walls you can see the harbour and Bodrum across the strait.
The castle was built and expanded by the Knights of St John of Rhodes between the 14th and 16th centuries, using many stones and carved fragments from ancient ruins. The moat that once separated the outer and inner fortifications is now a palm-lined avenue. The castle has been restored and is open to visitors, who can climb the walls for views over the harbour, the yachts and Turkey across the strait. You enter over a stone bridge spanning the avenue. Tickets cost a few euros, and in summer it stays open until evening. It is right next to the Hippocrates Plane Tree.
