Created during the Art Deco period (1927) by a renowned architect, Joseph Marrast, for the Boussard family, who had taken up residence in Lardy, this small 5,000 m² garden, which became a municipal park in 1989, is interesting as an approach to an architectural movement, an era - that of the 1925 International Decorative Arts Exhibition - and the art of gardens. In addition, this listed garden has benefited from the Heritage Lottery for a complete restoration to be completed in 2022. It was declared a Remarkable Garden by the French Ministry of Culture in 2024.
