The Château de Montluc, named after its famous owner Blaise de Monluc, is located in Estillac, in the French department of Lot-et-Garonne. Built in the 13th century, it was expanded in the 16th century in a Renaissance style by the Mondenard family. Blaise de Monluc inherited it in 1544 and undertook major works, including the addition of defensive bastions inspired by Italian fortifications. He also planned a funerary chapel for himself. The castle was modified to withstand the religious wars but was partially demolished in 1793. Blaise de Monluc lived here to write his commentaries but died in 1577, leaving the estate to his grandson. Over the centuries, the castle changed hands and was classified as a historic monument in 1958. Its architecture features a trapezoidal plan with an almost triangular interior courtyard.
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.
