Reinegg castle was built in the mid-13th century, and is recorded in 1263 as being owned by the countess Elisabeth von Eppan. Ten years later, ownership was transferred to count Meinhard II of Tyrol. Over the centuries, fiefs were granted to a number of different families until in 1635, Reinegg castle came under the ownership of Bolzano merchant David Wagner. In 1861 the Wagner family was elevated to Counts of Sarthein; they owned Reinegg castle until 1936 when it was sold. The castle is privately owned and not open to the public.
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.
