In the 17th century, Brussels was a centre for the lace industry. In 1695, during the Nine Years' War, King Louis XIV of France sent troops to bombard Brussels with artillery. Together with the resulting fire, it was the most destructive event in the entire history of Brussels. The Grand Place was destroyed, along with 4,000 buildings—a third of all the buildings in the city. The reconstruction of the city centre, effected during subsequent years, profoundly changed its appearance and left numerous traces still visible today.
