The Breno castle rises on a hill overlooking the town: the building was erected in the 12th century, then turned into a military stronghold at the time of the Venetian Republic (1400-1500) and finally, after being abandoned in 1598, it was reused as a stone quarry.
The castle however rises on a much more ancient site: probably the place where in the 10th-9th century BCE a prehistoric community settled.
You can reach the castle with a short walk (about 15 minutes) from the centre of Breno: the perimeter is closed by a battlemented boundary wall and by two towers. Inside you can admire the remains of the St. Michele church, of Longobard origin, then enlarged in the Romanesque period. The other buildings, the only remains of which are mostly the outside walls and the cellars with barrel vaults, were added during the Venetian reign.
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.
