Beautiful 18th century residence where Voltaire lived for 20 years, from 1755. The philosopher had a notable influence on Ferney: "When Voltaire bought the estate in 1759, Ferney had only 150 inhabitants. He had its marshes drained and developed many craft workshops there: tile-making, watchmaking, silk-making, etc. He took advantage of his fame to export his local products throughout Europe. When he died in 1778, Ferney had 1,500 inhabitants." (Wiki) Opening hours: From April 1 to September 30: 10 a.m. - 6 p.m. From October 1 to March 31: 10 a.m. - 5 p.m.

In the wide and more fertile plain between Geneva and St-Julien, various castles and permanent houses were built in the high and late Middle Ages. The sovereign center of the area was the Saconnez d'Arve castle, of which only a round tower stands today, probably the corner tower of an originally much larger complex. A kilometer further to the south is the Compesières permanent house, which occupies a special position among the castles in the area due to its role as a Johanniter commander. Only the residential wing has survived from the original overall complex. The church and the economic buildings were replaced by new buildings in the Middle Ages, and the outer fortified wall that once protected the entire building complex has disappeared today.
