On August 13, 1695, a 70,000-strong French army under Marshal François de Neufville, duc de Villeroi began a bombardment of Brussels in an effort to draw the League of Augsburg's forces away from their siege on French-held Namur in what is now southern Belgium. The French launched a massive bombardment of the mostly defenseless city centre with cannons and mortars, setting it on fire and flattening the majority of the Grand Place and the surrounding city. Only the stone shell of the town hall and a few fragments of other buildings remained standing. That the town hall survived at all is ironic, as it was the principal target of the artillery fire
The square was rebuilt in the following four years by the city's guilds. Their efforts were regulated by the city councillors and the Governor of Brussels, who required that their plans be submitted to the authorities for their approval. This helped to deliver a remarkably harmonious layout for the rebuilt Grand Place, despite the ostensibly clashing combination of Gothic, Baroque and Louis XIV styles.
