With its 12th century (!) octagonal crossing tower in chalkstone, this church is one of the few remaining Romanesque buildings in French Flanders. The Gothic stone spire is one century younger and the side aisles were only added in the 16th and 17th centuries. Since 1913, the church has been recognized as a Monument Historique.

It has been listed as a historic monument since 1947 together with the adjacent town hall1. The beffroi is 45 meters high and rests on four large pillars of brick and stone, two meters thick, which demarcate an interior space of six meters wide. It is of Baroque style and is part of the list of 23 belfries inscribed on the UNESCO World Heritage List in 2005 as part of the list of "Belfries of Belgium and France".

The current church took over the continuation of the Romanesque church consecrated in 1166 for the canon chapter inaugurated by Baudouin V in 1059. It was built between 1492 and 1634 and was carved from stone inside and out. Note the dates of progress of the work - the collegiate church of Saint-Pierre has been a parish church since 1803. When the successive wars (particularly the siege of 1710 and the bombing of August 8, 1944) repeatedly severely damaged the building it was always rebuilt according to the original plan3. The collegiate church was listed as a historical monument in 1862 and was restored several times in the 20th century (Wikipedia).
