Brindisi di Montagna Castle was built around 1200 and is situated on a large rocky ridge. The architecture is characterized by three main elements: The central part (a long the rocky ridge of the hill).The northern part, with the turret for lookout (later transformed by the Antinori family into the chapel of San Michele) and the southern part where there are few but significant wall traces embedded in the rocky elements.
Its defensive function is evident both from the presence of arrow slits and its position overlooking the intersection of the two routes leading to the fortress. It differs from the Swabian castles in terms of its layout, formal characteristics, and construction techniques, as it predates others built by Frederick II. Instead, it has undergone numerous transformations since the Angevin rule.
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.
