Barriers run close to the circuit and many experienced drivers have been caught out by them. A particularly famous part of the circuit is the wall on the outside of the exit of the final chicane before the start/finish straight. In 1999 the wall, which bears the name "Bienvenue au Québec" ("Welcome to Quebec") giving it the nickname "Mur du Québec" ("Quebec Wall"), ended the race of three Formula One World Champions, Damon Hill, Michael Schumacher and Jacques Villeneuve along with FIA GT champion Ricardo Zonta. Since then the wall has been nicknamed "The Wall of Champions". In recent years 2009 world champion Jenson Button (2005) and four time World Champion Sebastian Vettel (2011, during free practice) have also fallen victim to the wall.
