San Cibrao de Las hill fort (Castro de San Cibrao de Las) is a hill fort of the so-called castro culture. Rather than a single castle, it encompasses an entire fortified town or village. The place was inhabited from the second century BC to the second century AD. It flourished during the first century, at the beginning of Roman rule in Galicia.
The ruins are located on a 473-metre-high hill, covering an area 384 m long and 314 m wide. Unlike the other hill forts of the area, there are many straight walls and fewer curving structures.
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.
