The hill starts near the river Dender at 18 m and reaches the top of the Oudenberg at 110 m after 1,075 m at 9.3 per cent.

An extra stretch to the chapel ('kapel' in Dutch) at the summit was added in 1981 and climb became known as the "Muur-Kapelmuur".

With the finish in Oudenaarde, instead of Meerbeke, it was no longer possible to include it while the race was starting from Bruges.

When the start was moved to Antwerp for the 2017 race, the Muur was returned to the course, albeit as the eighth climb of the day, approximately 95km from the finish.

After omission of the Muur from the Tour of Flanders, it was announced that the climb would be in the 2012 E3 Prijs Vlaanderen, although not in the final.
