Castle of Neratzia (Kos Castle)

36° 53.8′ N · 27° 17.4′ E

The Knights Hospitaller fortress that guards the old harbour entrance, with a double wall and moat; you moor in its shadow. A bridge links it to the square of Hippocrates' plane tree.

Practical

Built by the Knights of St John (fortress begun in the 14th century, completed in the 16th: Wikipedia and Greek Wikipedia). After the 2017 earthquake the entrance was closed (Wikivoyage, as of July 2019); check whether it has reopened before planning a visit. Even closed, the walls and the Avenue of the Palms are the backdrop to every old-harbour berth. Ancient Agora ruins lie immediately inland.
