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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
