Hautvillers Abbey

Hautvillers Abbey, or more formally the Abbey of St Peter, Hautvillers, is a former Benedictine monastery in the Hautvillers commune of the Marne department in north-eastern France. The abbey remained active between 665 and the French Revolution of 1789. It housed the relics of Saint Helena, Empress and mother of Constantine, between 841 and 1819. One of its monks, Dom Pérignon, contributed to the development of sparkling wine in the Champagne region. The building has been classified as a monument of historical value since 1983.
