Besieged in 778 by Charlemagne, Château Fort de Lourdes became the residence of the Counts of Bigorre in the 11th and 12th centuries. In the 13th century, it passed into the possession of the Counts of Champagne, part of the kingdom of Navarre before coming under the crown of France under Philippe le Bel. It was ceded to the English by the Treaty of Brétigny in 1360, before returning to France at the start of the 15th century after two sieges. In the 17th century, the castle became a royal prison, and a state prison after the French Revolution, continuing in this role until the start of the 20th century when it became the Pyrenean Museum (1921) which it remains.
The castle's origins go back to Roman times. Various remains from this era (fragments of sculpture, votive offerings, wall foundations) were brought to light by military engineering work in the 19th century. However, a consequence of these works was the destruction of the greater part of the ancient walls. The finds are exhibited on the site.
Today, the oldest remains date from the 11th and 12th centuries and consist of the foundations of the present fortifications. The castle was reinforced in the 13th and 14th centuries (construction of the keep), and again in the 17th and 18th centuries.
The Notre-Dame-du-Château chapel houses the furniture of the former parish church of Saint-Pierre de Lourdes, destroyed in 1904. The present chapel is constructed with recycled material from Saint-Pierre de Lourdes.
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.
