Once you have climbed the Muur (Wall) and the Kapelmuur (Chapel Wall), you reach the top of the Oudenberg at the neo-baroque Chapel of Our Lady. The chapel on the Oudenberg was originally built as a place of worship by a hermit in 1294. In a later chapel in 1648, Our Ladys statue of grace was placed, so that the chapel became a place of pilgrimage for Geraardsbergen. In 1906, the chapel was replaced by a larger one with a domed roof. A carillon was added in 1955.
At the orientation table on the hilltop behind the chapel, you can see the whole region in clear weather. The orientation table indicates the altitude above sea level and situates the surrounding villages.
