Bruniquel castle is often called Châteaux de Bruniquel (i.e. castles, plural). This is because, two centuries after its construction, the castle was shared between two branches of the Comminges house, hence château vieux (old castle) and château jeune (young castle).
According to Gregory of Tours, the Merovingian Queen Brunehaut or Brunhilda built the first castle, 'château vieux' or 'castel Biel in the 6th century on the site of a Roman castrum.
Of the early 12th century castle, the only remains are partial foundations, parts of walls and the keep, the so-called Tour de Brunehaut. The site has been altered at various times, notably in the 13th, 15th, 17th and 19th centuries.
The 'château vieux' still has its keep from the 12th century, an era when the castle was the property of the Counts of Toulouse, and its residence from the 13th century. It also has a Renaissance gallery; other parts have undergone extensive remodelling in the 18th and 19th centuries. The keep is named after Brunehaut (la tour de la Reine Brunehaut).
The 'château jeune' dominates the confluence of the rivers Aveyron and Vère from a height of 90 m. It was built between 1485 and 1510 and was remodelled during the Baroque period. Its Renaissance gallery has six arcades.
The whole site has been classified as a historic monument since 1840 and has recently been restored. The castle is open to the public from March to mid-November.
References: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.
