Earlier this week I visited—for the first time—Notre-Dame du Raincy, the church built in 1922–23 by brothers Auguste and Gustave Perret. It is a seminal early example of reinforced concrete construction, and a tour-de-force of stained-glass (framed in concrete). I was wowed. What an amazing structure and thrilling space!
But here’s the headline: at nearly 100 years old, the building is falling apart. Rebar is visible and corroding in several places. A display inside the church says it is “a monument in danger.” Donations are sought.
