Inspired by the excavations in Pompeii, King Ludwig I of Bavaria commissioned the architect Friedrich von Gärtner to build an idealized Roman villa, which was completed from 1840–1848. On the ground floor are the reception and guest rooms, the kitchen and the dining room, grouped around two inner court yards, the Atrium with its water basin and the Viridarium with its garden in the rear section of the house.
The splendid decoration of the interior and the mosaic floors were copied or adapted from ancient models. Since 1994, original Roman works of art from the State Antiquities Collections and the Glyptothek in Munich are now also on display here. Among the most valuable exhibits in addition to the Roman marble sculptures, small bronzes and glas ses, are two marble thrones of gods. In addition, there is a different special exhibtion every year on an archaeological topic.
The Pompeiianum is surrounded by a small garden which was also only laid out in the mid-19th century. It was to be an 'ideal Mediterranean landscape', and still has a flavour of the warmer climes of southern Europe with its fig, araucaria and almond trees, as well as vines, Lombardy poplars and pines.
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.
