The castle of Asklipio (Asklepieion) was built in 1479 by Grand Master D'Aubusson at the site of an ancient lighthouse. In the Byzantine period, during the time of the Knights, the castle also offered the inhabitants of the surrounding villages protection against enemy attacks.
It had rectangular bulwarks and two massive towers. Its only gate leads to the south-east corner tower. Two construction stages can be distinguished. Inside the castle there are preserved ruins of buildings and two tanks. This is the place where a significant inscription dated 1473 and referring to the activity of Roman Catholic priests in the area comes from.
The castle is easily accessible, and a number of signs direct the visitors all over the route on the winding mountain. It is also easily seen from the valley below and the main road. If you are there by car, just follow the signs and make sure you park your vehicle in the designated parking area.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
