Onze-Lieve-Vrouw-Hemelvaartkerk, Baroque church in Ninove, Belgium

The Onze-Lieve-Vrouw-Hemelvaartkerk is a Baroque church in Ninove, one of the largest in Flanders. It has a brick exterior with lighter stone banding, a tall brick tower on the left with a green copper dome and cross, and a central projection capped by a dark onion-shaped cupola. The facade features tall, narrow arched windows on two levels.

The original Romanesque-Gothic abbey church, consecrated in 1174, was damaged between 1578 and 1580 and demolished in 1623; a temporary chapel followed in 1635. Abbot Jan David brought the plans from Rome in 1628, and construction of the present church began in 1640. Funding problems stalled the work for decades until Abbot Ferdinand Vander Haeghen resumed and completed it; the church was consecrated on 27 April 1727 by the Archbishop of Mechelen.

The abbey's patron saints were Cornelius and Cyprian; ten carved and painted scenes of their lives line the north and south walls. The church is still Ninove's parish church, and the abbot Ferdinand Vander Haeghen who finished the building also provided its furniture.

The church stands in Ninove's centre, with the tower separate from the main building and completed only in 1844. The interior is entered from the nave side; the Forceville organ of 1728 is inside. The tower was under restoration in 2023, so parts of the exterior may be scaffolded.

The 2022 archaeological dig in and around the church uncovered the remains of the 17th-century guesthouse and the 12th-century Romanesque church, plus a seal stamp belonging to Brother Balduinus. The tower, standing apart from the church building, was only finished in 1844 and was restored in 2023.
