The Château de Brissac is a noble mansion originally built as a castle by the Counts of Anjou in the 11th century. After the victory over the English by Philip II of France, he gave the property to Guillaume des Roches. In the 15th century, the structure was rebuilt by Pierre de Brézé, a wealthy chief minister to King Charles VII. During the reign (1515–47) of Francis I, the property was acquired by René de Cossé, who the king named as governor of Anjou and Maine.
During the French Wars of Religion, Château Brissac was made a possession in 1589 by the Protestant, Henry of Navarre. Severely damaged, the fortress was scheduled to be demolished. However, Charles II de Cossé sided with Henri of Navarre who soon was crowned King of France. In gratitude, King Henry gave him the property, the title Duc de Brissac and the money to rebuild the chateau in 1611. Its construction made it the highest château in France, its façade reflecting the influences of that century’s Baroque architecture. Through marriage, the Cossé-Brissac family also acquired the Château Montreuil-Bellay but later sold it.
In August 1620, Louis XIII and his mother, Marie de Medici, met to discuss their differences in the "neutral" territory of Château Brissac. A temporary truce between the two was reached but it did not last long and the Queen Mother was eventually banished.
The descendants of the Duc de Brissac maintained the château until 1792 when the property was ransacked during the Revolution. It lay in waste until a restoration program began in 1844 that was carried on during the 19th century by the Duke's descendants.
Today, the Château Brissac is still owned by a de Cossé family member. It has seven storeys altogether, making it the tallest chateau in the Loire Valley. The chateau is open to tours and its luxurious gilded theater hosts the annual Val de Loire festival. It was also used as a location for Brazilian celebrity magazine "Caras" until recently.
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.
