Château de Lordat castle dates back to the 9th and 10th centuries (mentioned first time in 970 AD). Around 1244 it was occupied by the Cathars during the crusade against the Albigensians. Lordat family abandoned the castle at the time of religious wars of France. Dismantled by the order of Henry IV in 1582, the castle fell gradually in ruins. The entrance is protected by a square tower which still has its original appearance.
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.
