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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
