The Hardt Foundation owns a wooded estate comprising several buildings: the main house, where guests stay, the library, the orangery and the greenhouse. The buildings, which date back to the 19th century, have been restored and modernised.
The grounds include a large natural lawn featuring a pond, a wooded area criss-crossed by a path suitable for walking or running, and finally an enclosed garden planted with fruit trees.
The Foundation’s estate is listed in Geneva’s inventory of properties worthy of protection.
