Sint-Pieterskerk stands on the south side of the Grote Markt, its broad Gothic nave and unfinished west towers giving it a slightly rugged look beside the lacework extravagance of the town hall opposite. The church was begun in the late 14th century in the Brabantine Gothic style and took over a century to complete; a planned central tower was abandoned after the foundations proved inadequate, leaving the silhouette we see today.
The interior is spacious and well-lit, but the main reason to visit is Dirk Bouts' triptych The Last Supper (1464–68), housed in the Treasury section of the church. This is one of the masterpieces of early Flemish painting, a monumental altarpiece commissioned by the Brotherhood of the Holy Sacrament. The central panel shows Christ at the moment of the institution of the Eucharist — calm, frontal, deeply serious — surrounded by apostles in a precisely rendered Flemish interior. The church also holds several other Bouts works and a collection of medieval ecclesiastical treasures. Entry to the Treasury requires a small admission fee.
