 In 1979, French entrepreneur Michel Guyot purchased the ruins of the Château de Saint-Fargeau and began restoring it with profits raised on-site.In late 1995, a study by Guyot's staff revealed the medieval foundations beneath the modern, brick structure, complete with a hypothesized plan of the original castle.Guyot built the existing château after some consideration, but began assembling funds and experts and opening negotiations with the French government to build a new castle.
