Saint-Omer Cathedral

Saint-Omer Cathedral is a Roman Catholic former cathedral, a minor basilica, and a national monument of France, located in Saint-Omer. It was formerly the seat of the Bishop of Saint-Omer, but the see was not restored after the French Revolution, being instead absorbed into the Diocese of Arras under the Concordat of 1801. The church is still commonly referred to as the "cathedral" however.
