Tavigny Castle dates to th late Middle Ages, and it may have been only a refuge tower that is now the central part of the castle. Its walls are long 10 meters, thick 2 meters and they had plenty of arrow slits. The lordship of Tavigny belonged at first to a family who wore already its name, but in 1360, it was already owned by the Ouren family, a powerful Middle-age family from the dutchy of Luxembourg. The central tower that was enclosed in walls with round towers in the corners got transformed little by little in a seignorial residence. The narrow windows and the arrow slits got substituted by large great picture windows and they made a very nice Louis XIII style ensemble
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.
