Brønshøj Church was built in the 1180s by Bishop Absalon, who is regarded as the founder of Copenhagen. This makes the Church the oldest intact building in Copenhagen. Originally dedicated to Saint Lawrence, Brønshøj Church is first mentioned in two papal briefs of 21 October 1186 and 25 March 1193. Limestone from Stevns Klint was used to build the Romanesque-style nave and choir. The red-brick Gothic tower was added in the 1400s. The porch was added in 1892, while the north-facing vestry was not added until 1942.
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.
