Built between the 1st and 2nd centuries AD, The Roman Amphitheatre of Venosa was deprived of many works and ornaments, which are currently located in other monuments in Venosa (many were used to erect the adjacent incomplete church). The first excavation was commissioned in the 19th century, where a series of bronzes, coins, and terracottas were found, but due to neglect, the ruins were buried again. Only in 1935 was everything brought back to light.
The Roman Amphitheater has an elliptical shape, with three levels, partly built above ground and partly created by terracing the ground on which it stands. The major axis measures 70 meters, while the minor axis is 40 meters. Based on these measurements, it is believed that this structure could accommodate approximately ten thousand spectators in its time. The lowest level is that of the arena, where the terrace of the 'podium' for important figures is located. There are two additional levels, supported by three concentric ambulatories.
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.
