Château de Cornusson was originally a medieval castle first mentioned in 1157. It was rebuilt in the 16th-17th centuries by La Valette-Parisot family. It saw some action during the Wars of Religion and held out several times against Protestant forces.
The Vignes family from Puylaroque acquired the château by marriage in the late 17th century. Apparently, it was pillaged during the Revolution and left in a terrible state. After that, it passed through various hands and sank into the obscurity of rural French life.
The Royal Palace was built in the first half of the 19th century as the Norwegian residence of King Charles III, who also reigned as king of Sweden and otherwise resided there, and is the official residence of the present Norwegian monarch. The crown prince resides at Skaugum in Asker west of Oslo. The palace has 173 rooms.
Until the completion of the Royal Palace, Norwegian royalty resided in Paleet, the magnificent town house in Christiania that the wealthy merchant Bernt Anker bequeathed to the State in 1805 to be used as a royal residence. During the last years of the union with Denmark it was used by the viceroys of Norway, and in 1814 by the first king of independent Norway, Christian Frederick.
