Having burned down in 1618, this town hall was rebuilt in 1620 by H. de Keyser. Restored in the 1960's, it rediscovered its 17C look, with its mullioned windows with leaded panes, and its low shutters. The façade, which overlooks the square and is decorated with shells, is dominated at the back by the former C15 keep, the only remaining trace of the original town hall.
