Located in the Kaylaka Park a few kilometers away from Pleven, Storgosia is ancient fortress dating back to the Roman era and containing the ruins of towers, gates, residential houses, a public storehouse and a large church believed to be constructed around the 4th century. Originally built as a road stop, it became a fortress to protect itself from raids and attacks.
The fortress existed until the end of the 6th century, when the settlement of the Slavs apparently led to its abandonment and during the rule of the Ottoman Empire the fortress was practically destroyed (probably in the 16th century), so that the stones could be used for the construction of a wall around the Turkish barracks in Pleven.
Archaeological excavations have been carried out on the site and a few basic structures of buildings can be seen.
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.
