The church of Saint Gommaire built between the 14th and 16th centuries is the most characteristic example of the flamboyant gothic style from Brabant. Members of the Kelderman family as well as Herman and Domien de Waghemakere are among the master craftsmen of this imposing building.
The tower is 83m high. Its gothic spire was burnt down in 1609 and in 1702 and was replaced by an octagonal rococo bell tower. This gave a particular aspect to the tower, which has been called the “pepperpot”.
The stained glass windows from the Middle Ages are certainly renowned and are known as the “Imperial windows” (1516-1519).They depict Emperor Maximilian of Austria and Mary of Burgundy and Phillip le Beau and Jean of Castile, who were married here in 1496.
The flamboyant rood screen in white sandstone from the 16th century is unique in its style and its luxurious ornamentation with its depiction of the sixteen Stations of the Cross. In the side chapels there are a number of paintings and a triptych of the Colibrant family. The interior is resplendent in rich furnishings, the astonishing baptismal chapel, of which a part came from the cloisters of Chartreuse, a Pieta and other life size statues. There is also a treasure of silver religious relics from the 17th to 19th centuries.
On the Sunday after the 10th October there is a procession in which the silver reliquary containing the relics of Saint Gommaire, weighing 800kgs, are carried by 16 inhabitants of Lier.
