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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
