There was originally a strong fortified castle Beritzholm few hundred meters from the present Bjärsjölagård Castle. It was built by Valdemar Atterdag in the 1300s and demolished in 1526. Peter Julius Coyet bought the estate from Crown in 1720. There was a lime factory in the beginning of the 19th century and two ovens still remain. The current main building was built in Rococo style in 1766 and the southern wing in 1812. The newer addition on the estate, was built in Romantic, German style in 1849-50, on a hill just south of the old castle. It is a three-story building flanked by two square towers. Today Bjärsjölagård is a hotel.
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.
