Until 1983, the last 300 meters of line 271 000, Roubaix-Wattrelos, ran here. At the other end, it connected to Belgian line 85 to Leupegem, Oudenaarde. The only 3.6 km long and never electrified line 271 000 no longer carried passenger trains after 1932.

From the early 1970s, the development of the new town in this area took shape with the construction of the Heron Park and the Heron Lake. The former hunting lodge was converted into a house divided into two rental apartments. In 1973, the building was acquired by the Public Institution for the Development of the New Town of Lille-East. In December 1982, the building, which had suffered damage since the expropriation, was returned to the municipality of Villeneuve d'Ascq. At the end of 1983, the municipality decided to have the building completely restored by the Compagnons du Devoir (a French craft guild) as part of a training program.

Marshland surrounded by a very smooth gravel road. Accessible by mountain bike. The marsh is very dry in summer.

The Templeuve sector was my first cobbled sector on the roads of the legendary Paris Roubaix race.

One of my favorite strips. Be careful in the bends. Too fast and you're in the fields, but too slow and you come to a complete standstill.

There are some decent MTB trail sections in this location. Quite narrow single track. You have to watch out for the exposed tree roots, there are plenty along these tracks. Fun to ride on and off road sections.
