In 1996, the owners of Fontenay asked British landscaper Peter Holmes to redesign the gardens of Fontenay, without attempting to reproduce ancient monastic gardens. These harmonious and impeccably maintained gardens with abundant vegetation are a real showcase for Fontenay. They embellish the visit in all seasons.
The gardens are organized around several spaces between buildings and behind the church, and offer a harmonious space that invites a leisurely walk. Three persons, assisted by outside companies provide maintenance throughout the year.
Amid these recent developments stands an imposing bicentennial plane tree, planted in 1780 and measuring approximately 40m high.
The gardens of Fontenay received in 2004 the National Label "Remarkable Garden" awarded by the Ministry of Culture.
