The Church of Saint Quentin is a Roman catholic parish church in Tournai, Belgium. The largely Romanesque building is located on the main square of the town, the Grand-Place. Known to have existed since the 10th century, the current building was built around 1200, but has been altered several times throughout history. In the late 15th century, a major reconstruction effort altered the chancel, created an ambulatory and replaced earlier side chapels. This reconstruction was partially financed by tapestry maker Pasquier Grenier and his wife Marguerite de Lannoye, who were also buried in one of the chapels. During World War II, the church was heavily damaged by German bombing in 1940 and subsequently reconstructed after the war. It opened again in 1968. The current facade and tower are reconstructions from this period. Inside, the church contains two Late Gothic wooden sculptures, made by Jean Delemer and painted by Robert Campin and dated to 1428. They are of art historical interest as early examples of such Late Gothic sculpture.
