Hotel? Office? Mushroom farm? Unused French churches get new roles.

French municipalities own more than 42,000 churches and Catholic dioceses around 2,500. But heritage experts told the French Senate this month that between 2,500 and 5,000 churches were at risk of being torn down by 2030.

To prevent that, from Nantes to Angers, Rouen to Caen, some of France’s most historic religious establishments are being transformed into concert venues, hotels, and nightclubs.

France has too many empty church buildings. No one wants to tear them down, but how do towns find new purposes for them while navigating sensitivities about those new roles?

For many, the transformations are seen as a blessing – a way to save France’s rich religious heritage. For others, it’s sacrilegious. But fewer French are attending church, and even fewer are opening their pocketbooks to save the structures. So city and religious officials are left with few choices: transform their dying churches or say goodbye to a piece of history. How do they decide which path to take?

“The French are very attached to their local bell tower, but how far are they willing to go to save it?” says Mathieu Lours, a historian of religious architecture and heritage. “Some people might not like the idea of transformation, but if no one invests in church maintenance, it will be torn down. We need to find uses for churches that respect the dignity and memory of the place, and create bonds in the community.”

An early morning haze streams in through the stained-glass windows of the Martray Chapel, basking the room in pastel yellow and green. Camille May walks through a maze of metal shelving, spraying nearly 100 cinder blocks of budding shiitake mushrooms with water.

Every few minutes he stops, takes out a carving knife, and cuts a flat-topped pearl from what looks like a giant chocolate brownie.

“See? This one is ready,” says Mr. May, holding the bite-sized treat up to the light before placing it in a plastic basket. By the end of the week, Mr. May and his business partner, Romain Redais, will have collected 70 to 100 kilograms (154 to 220 pounds) of mushrooms, destined for local restaurants and farmers’ markets.

While a church is perhaps an unlikely setting for a mushroom harvest, the conditions are perfect: warm and humid, with no major temperature variations. Since 2020, Le Champignon Urbain has been operating here, after winning a competition organized by Nantes City Hall in its search for a way to save the long abandoned 19th-century chapel.

Le Champignon Urbain is one of a growing number of projects breathing new life into churches across France that would otherwise fall into ruin. From Nantes to Angers, Rouen to Caen, some of France’s most historic religious establishments are being transformed into concert venues, hotels, and nightclubs.

For many, the transformations are seen as a blessing – a way to save France’s rich religious heritage. For others, they are sacrilegious. But fewer French are attending church and even fewer are opening their pocketbooks to save them. With thousands of churches across France at risk of ruin due to a lack of maintenance, both city and religious officials are left with few choices: transform their dying churches or say goodbye to a piece of history.

Camille May, co-founder of Le Champignon Urbain, harvests between 70 and 100 kilograms (154 and 220 pounds) of shiitake mushrooms each week out of the converted Martray Chapel in Nantes.
