Château Rothschild and its outbuildings, 19th-century castle in Pregny-Chambésy, Switzerland

Château Rothschild is a 19th-century castle near Lake Geneva featuring symmetrical wings and formal gardens arranged on spacious grounds. The building displays architectural details typical of Swiss estates from the 1850s period, with outbuildings integrated into the overall design.

Auguste Saladin-de Lubières built the neo-Greek Pavillon de Pregny here between 1822 and 1825, designed by Luigi Bagutti. In 1855 Baron Adolph Carl von Rothschild bought the estate, demolished the pavilion in 1858 and had George Henry Stokes, probably with Joseph Paxton, build the present château between 1858 and 1860. Childless, he left it in 1900 to his cousin Maurice de Rothschild, who bequeathed it to the State of Geneva on his death in 1957, keeping usufruct for the family.

The château's name honours the Rothschild family, who acquired the estate in 1855 and rebuilt it from 1858. Its rooms were arranged to display Adolph's collections: rock crystal and semi-precious stones from the Grand Duke of Baden, 18th-century furniture, and paintings by Goya, Rembrandt and Fragonard. Interior decoration was entrusted to Eugène Viollet-le-Duc.

The estate has three entrances: opposite the Place de Pregny, facing the Sainte-Pétronille church, and via the Chemin des Cornillons. The château itself is a private residence, so visits are not open to the public; the stables, aviary and riding school can be seen from the Route de Pregny.

The stables along Route de Pregny, designed in 1879 by John Camoletti in French neo-Renaissance style, carry the Rothschild family's arms and mix Meillerie stone, brick, white rock and slate under a bell tower. They later housed Benjamin de Rothschild's car collection before he built a 3,598 m2 underground garage nearby.
