Muur van Geraardsbergen is one of the most famous roads for cyclists in the world. It’s located in the center of the ancient city of Geraardsbergen, in the hilly southern part of the Belgian province of East Flanders.
The road, also known as Kapelmuur, Muur-Kapelmuur or simply Muur, is a steep narrow road with cobblestones. It has a maximun gradient of 19,8 and it’s often part of the Tour of Flanders cycling race.
The Wall of Geraardsbergen starts near the river Dender at 18m above the sea level, and reaches the top of the Oudenberg at 110 m, after 1,075m at an average percentage of 9.3 per cent. The climb is both a mixture of true cobblestones synonymous with Flanders, and the less treacherous paving “cobbles”.
