La Crête Abbey was a Cistercian monastery in the commune of Bourdons-sur-Rognon. It was founded in 1121 as the second daughter house of Morimond Abbey by Simon de Clefmont, after a failed attempt at a foundation in 1118 at the site now known as La Vieille-Crête. The abbey was very active in founding further monasteries: Les Vaux-en-Ornois in Saint-Joire (1130), Saint-Benoît-en-Woëvre (1132), Les Feuillants (1145) and Matallana in Villalba de los Alcores (1173).
It was suppressed during 1791 in the French Revolution, when the church and conventual buildings were mostly demolished. Little remains of the mediaeval structures, known from a plan of 1705, apart from the chapter house. The gate house of 1715 also survives.
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.
