The site of the Église Notre-Dame (Church of Our Lady) originally hosted a chapel dedicated to Saint John. After being heavily damaged and burnt by English forces during the Hundred Years' War, the church was rebuilt in the 15th and 16th centuries, remaining the 13th-century choir as the building’s oldest section.

The church features an imposing, 43-meter-high tower built in the 15th century. Following the dismantling of Orbec’s town castle in 1378, this fortified tower was heavily utilized as a military watchtower. The church underwent major neo-Gothic restorations and expansions starting in 1868.
