RONCHAMP, France — Completed in 1955, Le Corbusier’s hilltop chapel of Notre Dame du Haut in this hardscrabble patch of eastern France attracts some 100,000 supplicants each year, architectural and religious. If critics still sometimes blame Le Corbusier for inspiring generations of soulless, cookie-cutter housing projects and office parks, he remains the high priest of Modernism for singular works like this.
