Château de Brou was built in the second half of the 17th century by Paul-Esprit Feydeau, the Royal intendant. Important changes were made in the 18th century including the removal of a monumental staircase in the hall to allow to give more room to the bedrooms on the 1st floor. Instead, two staircases were built on the north side at each corner of the two wings of the castle. The dovecote is probably the oldest building on the property. Built in 1545, it stands on a circular basement with a central pillar. In 1844 the estate was sold due the Feydeau family had no descendants. It was acquired by Charles-Floréal Thiébaut. Since then, Château de Brou has remained in the possession of the same family.
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.
