Les Rochers was the estate of the Mathefelon family from the 12th century, before being passed by marriage to the Sévigné family in 1410. The family rebuilt the château in the early 16th century. Between 1644 and 1690, Madame de Sévigné stayed here and refurnished the house. She gave names to the paths through the gardens and in 1689 her son commis-sioned the French Gardens from Le Nôtre. In 1715, the Nétumières family bought the estate and carried out building and restoration works. Today there is a visitor centre at the 17th century Orangerie and exhibition about Madame de Sévigné and the Château des Rochers.
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.
