Archaeological Crypt of Notre Dame Tours and Activities

Hidden below one of the most admired attractions in Paris isthe Archaeological Crypt of Notre Dame Cathedral and a 262-foot (80-m) descent into the history of Paris' city center. The result of more than a hundred years of excavations, the crypt reveals the city's architectural layers, including ancient ruins from the Gallo-Roman town of Lutetia—the predecessor of present-day Paris. Follow one of two itineraries through the ruins to see 3rd-century homes, a 4th-century bathhouse, and the ancient port on the River Seine. Also inside the crypt are the remains of a two-story, 12th-century home, an 18th-century hospital, and shops built along the rue Neuve Notre Dame in the second half of the 12th century.

Multimedia exhibits inside the crypt guide visitors through centuries of historical development in Paris, making it a must-see for archaeology- and history-buffs. The crypt also contains an exhibit on the construction of Notre Dame Cathedral, and can be visited free of charge with the Paris Museum Pass.
