Le Corbusier not only designed and built churches, but also engaged intensely with religion and faith and, through his oeuvre, had a significant impact on church architecture of the twentieth century. The book explains Le Corbusier’s relationship with religion; it introduces his designs for La Sainte-Baume, the Chapel of Notre Dame du Haut de Ronchamp, La Tourette monastery, and the church of St. Pierre, and investigates his impact on the ensuing modern church architecture in Europe. This includes the Jubilee Church by Richard Meier, the Ignatius Chapel by Steven Holl, the Santa Maria Church by Álvaro Siza, Tadao Ando’s Meditation Space, and the Chapel of Reconciliation by Reitermann & Sassenroth. For the third edition, the introduction, the conclusion, and the bibliography have been revised and supplemented.
