[1] The Château d'Ouchy ("Castle of Ouchy") is an old medieval castle of Lausanne (Switzerland) that has since been converted into a hotel.


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.
Palais de Rumine, where the Treaty of Lausanne finalising the break-up of the Ottoman Empire after WWI was signed in 1923, safeguards the city’s fine arts museum. Works by Swiss and foreign artists, ranging from Ancient Egyptian art to Cubism, are displayed, but the core of the collection is made up of works by landscape painter Louis Ducros (1748–1810).

The hotel opened in 1861 and the current main building was constructed in Art Déco and neo-baroque style in 1908.
In 1923 the Treaty of Lausanne was signed at the Beau-Rivage Palace.
