As early as the 13th century, there is a hall covered with wooden slats, the "scindules", a kind of scrap wood that makes it vulnerable to fires and gales.It will be rebuilt several times. Nearby, a large stone hollowed out of various cavities serves as a measure for the goods. Agents of the count circulate between the benches to levy Leiden, a tax on certain products, such as meat and wheat. The square is decorated in its center with a fountain with a wooden basin, near which is the pillory where criminals are exposed to the eyes of the population.
