The Kemmelberg, the highest point in the region, is the toughest climb and the emotional centrepiece of the race. Named after Camulos, the Celtic god of war, the Kemmelberg's summit lies atop a thickly wooded ridge which was the scene of the Battle of the Lys in April 1918, in which more than 200,000 soldiers died. The climb has been controversial in the past because of several severe crashes in its descent. In 2007 French rider Jimmy Casper crashed heavily, suffering numerous facial and other fractures. In 2016 the climb was addressed by its steepest road for the first time in more than 20 years.
