Church of Saint-Denis
The church of Saint-Denis is recognisable by its enormous 13th-century bell tower, the oldest in the North of France. The church was favoured by the Collège de Saint-Omer which was run by English Jesuits. Many English and American Catholic families sent their children there to study, despite Queen Elizabeth I's prohibition. The interiors are particularly rich in examples of numerous artistic movements from the 15th to the 19th century. Its classical barrel-vaulted sanctuary, interiors and furnishings date from an 18th-century reconstruction.
