Crypte Archéologique du Parvis Notre-Dame lies beneath the square before Notre-Dame Cathedral in Paris, revealing archaeological layers beneath the city. The museum presents remains from Roman times through the nineteenth century. Excavations uncovered a Roman bathhouse, part of a fourth-century city wall, and medieval foundations for homes and workshops. A medieval quay marks the former edge of the Seine. The crypt also holds foundations of earlier churches that stood here before Notre-Dame Cathedral was built in the medieval period. These stones connect worship with medieval daily work. The archaeological layers show how buildings, streets and riverside activity changed across Parisian history beneath the square. The site emerged during excavations planned for an underground car park. Instead of parking structures, archaeologists found evidence of Roman, medieval and later Paris beneath the public square. The museum opened to the public after these discoveries. Paris Musées manages the crypt, which remains accessible to people with mobility challenges and preserves ancient structures in place. Visitors can walk among these ancient remains.
