The Château de Saumur, originally built as a castle and later developed as a château was originally constructed in the 10th century by Theobald I, Count of Blois, as a fortified stronghold against Norman predations. It overlooks the confluence of the Loire and the Thouet. In 1026 it came into the hands of Fulk Nerra, count of Anjou, who bequeathed it to his Plantagenet heirs. Following its destruction in 1067, the castle was rebuilt by Henry II of England in the later 12th century.
In the early part of the 13th century, Philip II of France made Saumur part of his royal domain. The page for September in the Tres Riches Heures du Duc de Berry depicts the Chateau as it looked in 1410. It changed hands several times until 1589 when the Protestant King Henri IV (of France and Navarre) gave the castle to Duplessis-Mornay.
In 1621 the castle was converted into an army barracks. Nearly two centuries later it was converted into a state prison under Napoleon Bonaparte. In the first part of the 20th century, the city of Saumur acquired the castle and began a restoration program to house the museum of the decorative arts. In line with the Saumur area's equestrian tradition and its famous "Cadre Noir", the castle also serves as a Museum of the Horse. The castle has a dungeon and watchtower, and houses the Musée de la Figurine-Jouet, a collection of very old toys and figurines of soldiers, kings of France, and clowns.
The Château de Saumur has been listed as a monument historique by the French Ministry of Culture since 1862. As of 2008, there are a total of 46 buildings and structures in Saumur which are designated a Monument Historique - see the French national database Mérimée. Most of the monuments are built in the lovely soft local stone known as tuffeau. Amongst the most important monuments are the great Château de Saumur itself which stands high overlooking the town, and the nearby Château de Beaulieu which stands just 200 metres from the south bank of the Loire river; designed by the renowned architect Jean Drapeau, it is recognised for its light and elegant architecture. Amongst the other Monuments Historiques are the church of Saint-Pierre in the Place St Pierre in the centre of Saumur, and the Château de Briacé which is located on the north side of the river.
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.
