Dun Bharabhat is an Iron Age galleried dun (ancient fort) or 'semi-broch' situated on the island of Great Bernera. The broch stands high above the water, and is connected to the shore by a 30 metre causeway. The building is a D-shaped broch with a wall of uneven thickness. The broch measures 17 metres by 13 metres externally. The walls stand to a maximum height of 3.4 metres. The building is badly ruined, and strewn with rubble. The entrance is on the northwest but cannot be seen. Nevertheless, it is considered one of the best preserved of all the island duns.
A ground level gallery can be seen at the east end of the high wall where an opening shows a small part of it. A stairway is also present in this part of the building. The upper part of the wall contains the remains of two superimposed galleries. The opening of a longitudinal gallery or cell running northeast from the entrance can still be seen at the west end of the high wall. The intra-mural galleries are evident from the shore.
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.
