L'église Saint Julien
The church was constructed starting in 1394 and consecrated in 1415. The left-hand tower was finished in 1462 and crowned with a high steeple in 1465. The church was hit by lightning and burned in 1817. The apse of the choir, the tower, and the western portal escaped destruction. The carillon has 41 bells with a range of 3 octaves.
The highlight of the "Gallo-Roman space" are three restored 2nd century Celtic riverboats excavated from an archaeological site. They are the only ones of their kind on display in Belgium and are encased in a huge display box. The other floors display life during antiquity, from the viewpoint of different professions: fishermen, potters, shoemakers etc.

The main square is surrounded by buildings from many eras and architectonical styles. The oldest is the Maison espagnole, dating from 1564 that has been restored (however clumsily) and is used by a bank. There are many 18th century houses built during French rule in different styles, and they host different businesses. At the corner of the square and rue aux Gades is the Grand-garde, a butcher's hall that was built by the Dutch in 1821 to replace an older hall. Le Palace, also known as salle des fêtes is a beautiful Art Nouveau building from 1919.
