Esplanade du Champ-de-Mars, Public esplanade in Lille, France

The Esplanade du Champ-de-Mars is a large open square in Lille with a flat layout that extends along the Moyenne-Deûle river. Walking paths crisscross the space, with designated parking areas and green sections designed for people to rest and walk.

The site was created in 1670 during Vauban's military transformations of Lille and remained a restricted military zone where permanent structures could not be built. Only in the late 1800s did it transition to public use and open development.

The Foire de Lille, later the foire aux manèges, has occupied part of the esplanade since 1836, and the fairground and circus area still sits between the two car parks. Rows of trees along the Façade de l'Esplanade date back to Vauban's era. Large exhibitions were held here in 1902 and 1920.

The space is easy to walk through with well-maintained paths, particularly along the river where you can move freely. Parking is available throughout the area, and trees provide shade in several sections for those wanting to rest.

Scattered throughout the esplanade are remains of old communication walls that once linked the Citadel to surrounding fortifications. These stone remnants tell visitors about the strategic importance this space held during its military past.
