The Jardin botanique de Bayonne (3000 m²), also known as the Jardin botanique des Remparts, is a botanical garden located at the Avenue du 11 Novembre and Allée de Tarride, Bayonne, Pyrénées-Atlantiques, Aquitaine, France. It is open Tuesday through Saturday in the warmer months; admission is free.
The botanical garden was established in the late 1990s atop an existing 7-meter high bastion by Vauban, within the city's protected sector between its cathedral and ramparts, and overlooking its war memorial. It contains about 1,000 taxa arranged in 11 groupings, including bamboos, a fine collection of Japanese maples, fountain, waterfall, pond, Japanese bridge, and walkways created from recycled materials.
