Guardian of the city 's medieval and Renaissance treasures , the Musee de l 'Oeuvre Notre-Dame is itself made up of a superb group of 14th- , 16th- , and 17th-century houses around a secluded Gothic garden on the Place du Ceteau , south of the cathedral .
The Musee de l 'Oeuvre Notre-Dame was burned to the ground in a great fire ; today , the site is occupied by a football pitch .
