The Le Quesnoy fortifications are listed as part of the UNESCO World Heritage site 'Vauban's Major Fortifications'.
The town was a strategic stronghold that changed hands multiple times between France and the Habsburg Netherlands before the 1659 Treaty of the Pyrenees.
The bastion design utilizes a 'bastion trace' geometry, which eliminates blind spots for defenders by projecting walls outward.
During World War I, the town's fortifications were the site of a notable liberation by the New Zealand Division in 1918.
The moats surrounding the bastion were historically designed to be easily flooded to deter infantry and siege engines.
The current preservation work is part of a regional effort to maintain northern France's military heritage trail.
The Green Bastion, or 'Bastion Vert', is a prominent component of the Vauban-designed fortifications surrounding the town of Le Quesnoy. These defensive structures were commissioned in the 17th century to reinforce the French border against the Spanish Netherlands. The site is characterized by its significant earthworks, deep moats, and stone masonry walls that have been preserved despite multiple historical sieges. The ramparts are part of an integrated park system that surrounds the old town center. Visitors can traverse the perimeter via maintained walking paths that trace the lines of the former military engineering. The bastion serves as a focal point for understanding the military architecture developed by Sébastien Le Prestre de Vauban. It remains a public space integrated into the natural landscape, featuring water-filled defensive ditches. The fortifications have transitioned from military utility to a recreational circuit used by locals and tourists.

Bring binoculars for birdwatching, as the moats and overgrown bastions have become a local refuge for waterfowl and wildlife.
Check the local tourist office map to identify the specific sections of the circuit that are currently open for pedestrians.
