The King Baudouin Stadium (formerly Heysel Stadium) is the largest in the country and home to the national teams in football and rugby union. It hosted the final of the 1972 UEFA European Football Championship, and the opening game of the 2000 edition. Several European club finals have been held at the ground, including the 1985 European Cup Final which saw 39 deaths due to hooliganism and structural collapse. The King Baudouin Stadium is also home of the annual Memorial Van Damme athletics event, Belgium's foremost track and field competition, which is part of the Diamond League. Other important athletics events are the Brussels Marathon and the 20 km of Brussels.
