The first Saint-Rémy church, of which only the tower remains today, was built in the 13th century. It was built at the foot of the hill on which stands the castle. The church gradually fell to ruins and the new Saint Rémy church was built in the heart of the town. It was Thomas Bouchard, deputy mayor and treasurer of the parish who laid the first stone in 1522. The gothic centre, surrounded by an ambulatory and radiating chapels, was completed in 1545, but the influence of the first French Renaissance was already visible in the décor.
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.
