Built between 1935 and 1938,[1] and qualified as a prototype of Brussels' Art Deco, this building illustrates the leading role the style played in public architecture during the interwar period.

[1] The building has important interior and exterior decorations made by such artists as Victor Rousseau, Georges Baltus, Canneel, Stoffyn and Tricot.

[citation needed] During World War II, the Municipal Hall suffered from bombings in Forest that lead to serious damage to the façade and the entrance portal to the Chaussée de Bruxelles/Brusselsesteenweg.

Forest's Municipal Hall is also listed as protected immovable heritage by the Department of Monuments and Landscapes of the Brussels-Capital Region.

[1] The capitals of the portals' pillars are decorated with bas-reliefs that evoke family life and local trades such as brewing, laundry or shoemaking.
