Château de Malmaison
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. It contains a number of buildings dating to the 18th century onwards, including an interesting dovecote built in 1817.
