Complexe Sportif Flénu

The Complexe Sportif Flénu sits on the site of a former swimming pool in the village of Flénu. It has a capacity of 500, where the playing surface is natural grass. The complex includes other pitches, one of which is artificial turf, but the main field remains the focus for FC Flénu, the amateur club that considers itself the successor to several dissolved local teams. The club was founded in 2001.

In July 2025, a major fire destroyed the sports hall. The building had been closed for two years and was scheduled for demolition, yet the blaze produced a large plume of black smoke. Fortunately, no injuries were reported.

FC Flénu occasionally hosts other teams, including Sporting Bruxelles, but there is no evidence that it serves as the official home ground for R. Standard de Liège's youth teams. A friendly match between FC Flénu and Standard de Liège 16 FC in January 2027 took place here.

The address is Rue des Produits 28, and the location is firmly within the municipality of Mons. The opening year of the complex is not found in available sources, nor is the specific builder known.
