Observatory of Religious Heritage

The Observatoire du Patrimoine Religieux (OPR), or Observatory of Religious Heritage, is a French non-profit association founded in 2006 by Béatrice de Andia. It works to preserve and promote France's religious heritage across all faiths and eras. With more than 250 members throughout France, the OPR operates a participatory online census of religious buildings—chapels, churches, Protestant temples, synagogues, mosques, Buddhist pagodas, and more—aiming to document the estimated 100,000 religious edifices in the country. As of January 1, 2024, the census listed 74,100 buildings. The organization also monitors threats to religious heritage, advises local officials and project leaders, provides legal and technical expertise, and organizes visits, conferences, and publications. It acts as a watchdog, alerting the public and authorities to demolitions, fires, vandalism, and other risks. The OPR is headed by Édouard de Pradel de Lamaze, president since 2015. Its website serves as a central hub for news, the census, and resources on French religious heritage.

The Observatoire du Patrimoine Religieux (OPR) was founded in 2006 by Béatrice de Andia, emerging from the observation that religious heritage was largely absent from public policies at the beginning of the 21st century. Despite being France's premier heritage in terms of history, variety, and territorial presence, religious buildings lacked coordinated attention. The OPR was created to share the reality of this vast museum with the public. Its first major initiative was the creation of a participatory census of all religious edifices in France—chapels, churches, Protestant temples, synagogues, mosques, Buddhist pagodas—aiming to gather them on a single platform, interfaith and exhaustive. This census revealed that nearly 100,000 religious buildings exist in France, far more than the approximately 42,000 parish churches. Soon after, the OPR confronted the phenomenon of church demolitions, leading it to intervene with local and national actors to halt the trend. It began alerting public opinion, advising local elected officials, and calling on national decision-makers. Over the years, the OPR expanded its missions to include legal and technical advice, field surveys with university students, publications, and public events. By January 1, 2024, the census had documented 74,100 edifices. The organization continues to monitor threats, advocate for preservation, and promote awareness of France's religious heritage.
