The Buurkerk is a former medieval parish church. It is documented as being burned in in 1131, 1173, 1253 and 1279. The tower dates from 1370, but was never finished. In 1577 a cannon was installed in the church tower, aimed at Vredenburg (castle) where the Spanish soldiers there were under siege by the Utrecht schutters. Around 1580 the church endured the protestant reformation and in 1586 it was formally handed over to the protestants, who whitewashed the wall decorations and removed the choir to make room for a street. In 1975 the church fell into disuse and in 1984 it became a museum.
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.
