Arboretum de la Fosse

The Arboretum de la Fosse (25 hectares), sometimes known as the Parc botanique de la Fosse, is a historic, private arboretum located in Fontaine-les-Coteaux, Loir-et-Cher, Centre-Val de Loire, France. It is open several days per week in the summer; an admission fee is charged. The arboretum was established in 1751 by Alexandre-Sébastien Gérard, an advisor to Empress Josephine on the Château de Malmaison, and is one of France's oldest arboreta. It has subsequently been owned and maintained by 7 generations of the same family, and in 1978 was the first arboretum entitled to protection by the Monuments Historiques designation.
