On his death, Gabriel de Rumine, son of Russian nobility, left the city of Lausanne 1.5 million Swiss Francs to erect a building for the use of the public. Building began in 1892 according to the design of the Lyonnais architect Gaspard André. The building was inaugurated on the 3 November 1902, although building work continued until 1904.
On 24 July 1923, the Treaty of Lausanne was signed in Palais de Rumine.
It housed facilities such as the library of the University of Lausanne, and scientific and artistic collections belonging to the Canton of Vaud. In the 1980s, the university moved to its current location by Lake Geneva due to lack of space, and the Palais was restructured.
The building currently hosts one of the three sites of the Cantonal and University Library of Lausanne. Additionally, it contains several museums like Musée cantonal des beaux-arts (Cantonal Museum of Fine Arts), Musée cantonal d'archéologie et d'histoire (Cantonal Museum of Archeology and History) and Musée monétaire cantonal (Cantonal Museum of Money).
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.
