The Botanical garden of Upper Brittany is located on the village of Le Châtellier (Ille-et-Vilaine), approximately 10 kilometres (6.2 mi) from the city of Fougères, between Rennes and the Mont Saint-Michel, near the A84 motorway.

In 1796, the old manor house was the headquarters of an uprising against the government of the French Republic led by Count Joseph de Puisaye.

[2] In 1847, the land surrounding the pond in the park was redesigned as an English romantic landscape garden.

It featured paths that follow the terrain, and a view of the lawn in front of the house and the church tower in the village.

The French Ministry of Culture classified the Parc botanique de Haute-Bretagne as a Jardin remarquable, notable gardens of France.
