Location
The park is part of the castle with the same name, situated on a height behind the Châtillon parish church.

History
The park, like the castle and the French styled Renaissance garden, assumed its current conformation in 1706. In fact, thanks to Paolina Solaro di Govone, wife of Giorgio Francesco di Challant, the castle was fully reconstructed and new trees were planted in the park. Nowadays the park belongs to the countness Claudia Passerin d’Entrèves.

Description
Various trees were identified in this park as “monumental plants”, of different varieties, protected by a specific regional law.
The park covers about 3 hectares but only 2 hectares are accessible and constantly monitored. A sign has been placed before all the monumental plants listing their characteristics.
