Monastery Mont G is a monastery complex founded and built by Walloon Carmelites during the First World War. In the late 1920s, an order of missionaries took over the complex. They established a study house and novitiate, and from the late 1960s, a retreat center. The most beautiful part of the monastery complex is the neo-Gothic monastery church, dedicated to Our Lady of Carmel. The church is a three-aisled hall church. It was designed by a Brussels architect. To the right of the narthex, we see a square tower with three sections, and a smaller, polygonal stair tower to its left.

At the turn of the millennium, the monks decided to abandon the complex and it was purchased by the municipality, which built a retirement home on the site, among other things. Ten years later, the existing monastery complex was sold to a developer with the intention of building a hotel/restaurant and several assisted living quarters.
