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.

Permanent house of Compesières, occupies a special place among the castles of the region due to its role as Commander Johanniter. Of the original ensemble, only the residential wing has survived. The church and economic buildings were replaced by new buildings in the Middle Ages, and the outer walled enclosure that once protected the entire building complex has disappeared today.
