Berat Castle dates mainly from the 13th century and contains many Byzantine churches in the area and Ottoman mosques. It is built on a rocky hill on the left bank of the river Osum and is accessible only from the south.
After being burned down by the Romans in 200 B.C., the walls were strengthened in the 5th century under Roman Emperor Theodosius II to protect from Barbarian incursions into the Balkans. They were subsequently rebuilt during the 6th century under the Emperor Justinian I and again in the 13th century under the Despot of Epirus, Michael I Komnenos Doukas, cousin of the Byzantine Emperor. This last phase can be seen as a Monogram formed by red bricks set in a wall of the castle. The castle was under the rule of John Komnenos Asen in the mid-14th century The main entrance, on the north side, is defended by a fortified courtyard and there are three smaller entrances.
The fortress of Berat in its present state, even though considerably damaged, remains a magnificent sight. The surface that it encompasses made it possible to house a considerable portion of the cities inhabitants. The buildings inside the fortress were built during the 13th century and because of their characteristic architecture are preserved as cultural monuments. The population of the fortress was Christian, and it had about 20 churches (most built during the 13th century) and only one mosque, for the use of the Turkish garrison (of which there survives only a few ruins and the base of the minaret). The churches of the fortress were damaged through years and only some have remained.
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.
