De Schorre, Provincial recreation area in Boom, Belgium

De Schorre is a provincial recreation area in Boom featuring rolling landscapes with open fields, wooded sections, and water features throughout its grounds. The site includes continuous walking and cycling routes alongside designated spaces for different outdoor activities.

From the 19th century, clay was dug here by hand and later by excavators for Boom's brickworks, leaving the artificial slopes and pits visible today. After the brick industry declined in the 1960s and 1970s, the pits filled with rainwater and groundwater. The Province of Antwerp bought the 75-hectare site in 1986 and turned it into a recreation domain, keeping two excavators of the Verstrepen and Van Herck brickworks as relics.

The name refers to the tidal marshes (schorren) along the Rupel that once covered this ground. Since 2005 Tomorrowland has been held here each summer, and from June to mid-August the domain is closed or only partly open to recreation. Sculptures made with the festival remain, including Arne Quinze's 'One World', Thomas Dambo's troll forest and the mosaic 'Stairway to Unity'.

The steep, artificially excavated slopes make large parts of the terrain difficult or impossible to reach for wheelchair users and people with limited mobility. From June to mid-August the domain is closed or only partly accessible for recreation because of Tomorrowland. The oval clearing ringed by a paved track is the central orientation point, with a narrower path looping around it.

Two preserved excavators used by the brickworks Verstrepen and Van Herck for large-scale clay extraction still stand on the domain. A historic excavator was left behind in the clay pit and remains there, without any explanatory signage and in a state of progressive decay.
