Église collégiale Saint-Ursmer, Romanesque church in Binche, Belgium.

The Église collégiale Saint-Ursmer is a largely Gothic church whose lower tower and west side of the nave remain Romanesque. The tower rises in brick dated 1583, crowned by a slate lantern from 1621 and an onion-shaped bulb replaced around 1950. The nave and aisles have a Baroque vault left without plaster, and the north side has three chapels under a single roof from the first half of the 16th century.

A Romanesque church of the Moustier Sainte-Marie monastery, founded in 1124, stands on the site; its lower tower, north choir wall and west nave face survive. In 1409 the secular chapter of Lobbes Abbey moved to Binche with the relics of Saint Ursmer, and the church became the collegiate Saint-Ursmer. The Gothic rebuilding began with the choir and lasted about a century. The tower was fully renovated in 1552, a fire ravaged church and palace in 1554, and the tower was raised in red brick in 1583.

The parish treasure survived heavy losses during the French period. Its main pieces are the silver arm reliquary of James son of Zebedee, attributed to Godfroy de Huy around 1150-60, the silver arm reliquary of the apostle Peter by Hugo d'Oignies around 1230, and the reliquary bust of Saint Ursmer.

The church is located in Binche at Rue Haute 5 and features a magnetic loop system for visitors with hearing impairments. Visitors should check if there are specific viewing times, as this is an active place of worship.

The onion-shaped top of the tower is not medieval: the lantern was built in 1621, and the bulb itself was replaced around 1950. The brick first storey below it dates from 1583, when the tower was raised after the fire of 1554.
