Semi-buried washhouse covered with a timber-framed roof decorated with festoons. In the 19th century, washhouses served an important social function. They were one of the few places where women could exchange ideas. Washing clothes was also physically very strenuous. Therefore, practicing this activity collectively made it more bearable. Contrary to popular belief, washhouses most often allowed washerwomen not to wash clothes, but to rinse them.

Ravel with a gentle slope. Pleasant for traveling from Olloy to Oignies by road or city bike. For mountain bikes, other paths are much nicer.
