The factory complex originally included over 150 buildings designed to be blast-resistant, many of which remain scattered throughout the park.
The site was historically chosen for its strategic location between the Canal de l'Ourcq for transport and the surrounding forest for natural camouflage.
The gunpowder factory was decommissioned following a major explosion in 1973, leading to the eventual conversion of the site into a public park.
The park is home to a protected population of rare orchid species and diverse amphibians inhabiting the marshy sections.
Many of the park’s pathways follow the original narrow-gauge railway tracks used to transport hazardous explosive materials across the site.
Parc Forestier National de la Poudrerie is a 137-hectare protected green space situated along the Canal de l'Ourcq in the Seine-Saint-Denis department. The park occupies the site of a former state-run gunpowder factory that operated from 1867 to 1974. Visitors can explore the Musée des Poudres, which documents the site’s industrial history and the chemical processes used in munitions manufacturing. The park features diverse ecosystems, including wooded areas, marshes, and meadows, serving as a wildlife corridor. Recreational amenities include sports pitches, jogging circuits, and cycling paths that connect to regional greenways. It is a state-managed site, designated as a Sensitive Natural Area (ENS) to preserve its specific biodiversity. The landscape retains traces of its industrial past, including historical service buildings and remnants of former transport tracks. It serves as a significant recreational buffer zone for the urban populations of Sevran, Villepinte, and Livry-Gargan.
