Designed by the architect Jules Jacques Van Ysendyck [fr] in neo-Flemish Renaissance style and completed in 1887, it is located at the centre of the Place Colignon/Colignonplein.

The first stone was officially laid on 15 March 1885 and the building was inaugurated on 21 July 1887[1] by King Leopold II.

The architect's son, Maurice Van Ysendyck [fr], was charged with the reconstruction, which began in 1912 and lasted until 1915.

On that occasion, the building was significantly enlarged at the rear by adding an extension in Italian neo-Gothic style to the U-shape, thus turning it into a quadrilateral.

On 13 April 1995, the Municipal Hall was listed as protected immovable heritage by the Department of Monuments and Landscapes of the Brussels-Capital Region.
