The Great Mosque of Brussels located in the north-western corner of the park. It is the oldest mosque in Brussels, and is seat of the Islamic and Cultural Centre of Belgium.
The original building was built by architect Ernest Van Humbeek in an Arabic style, to form the east pavilion of the National Exhibition in 1880. The pavilion housed then a monumental fresco; “Panorama of Cairo” which was a major success. However, the lack of maintenance in the twentieth century caused the building to gradually deteriorate.
