The ancient village of Roccavaldina was conquered by Romans, Byzantine and Arabs. Later in the Middle Ages, it was ruled by Roger I, who built numerous monasteries with the aim to spread the Christian culture over the area. The Valdina Castle was built as a stronghold in the 16th century and later transformed in a prive aristocratic house; the Chemistry Museum is an ancient shop created in 1628 which contains over 200 apothecary jars made with the local ceramics.
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.
