Église Notre-Dame du Raincy

At the beginning of the 20th century, Le Raincy was a small parish church for suburbs whose population was rapidly growing.

In 1918, the parish priest of Le Raincy, Felix Nègre, proposed to build a church to commemorate the French victory in the Battle of the Marne in 1914.

Rather than attempting to simulate masonry, the new material was used on its own terms, with standardized elements, slender supports, and thin membranes pierced by windows.

The completed church received widespread favorable attention, influencing architectural thought at a time of rebuilding and economic recovery.

Deterioration was evident by the 1960s, and analysis showed that the original concrete mix contained an excess of lime and water.
