The Abbey of Saint-Pierre at Hautvillers is a Benedictine abbey founded in 650 CE. Most of the medieval buildings were destroyed during the French Revolution; what stands today is largely an 18th-century reconstruction, now owned by Moët & Chandon and used for storage of champagne. The abbey church, however, is open and contains the tomb of Dom Perignon — a simple black marble slab set in the floor before the altar that has become a genuine pilgrimage site for wine lovers.
The abbey is visible from the village and the church can be entered during visiting hours. The cellar master's actual workspace — the vaulted cellars — is not generally open to the public, but Moët & Chandon organises occasional visits. Even without the cellars, the church and the dom's tomb repay the trip.
