At the harbour entrance to Kos Town stands the Venetian castle of The Knights Of St. John.
There are many similarities of character and of history between Kos and Rhodes. Both have their capitals and principle harbours at their most northerly point , close to the rugged Turkish coast. The same popular name , Mandraki (meaning sheepfold), was given to their harbours, and the entrance to both of them was guarded by a fifteenth-century castle built by the Knights of St. John.
Close by you will find the remains of the Agora and in another part of the town are the ruins of a Roman amphitheatre...
Dont miss the huge old twisted tree known as Hippocrates Plane Tree even though it dates back only 600 years.
