Origin and history

The Sainte-Thérèse chapel of Montmagny, located in Val-d'Oise in Île-de-France, was built between 1926 and 1927 under the impulse of Abbé Garnier. Conferred to the brothers Auguste and Gustave Perret, pioneers of reinforced concrete, she inspired herself from the church of Raincy and adopted a basilical plan. Its bell tower, 32 meters high, dominates the facade, while its bedside houses a fresco of Christ crucified with Saint Thérèse, painted by Valentine Reyre, co-founder of the Workshops of Sacred Art.

Ten years after its completion, Reyre added a cross path to fourteen stations. Classified as a Historical Monument in 1997, the chapel illustrates the religious architectural innovation of the 20th century. In 2025, the Cardinal's Building Association allocated 250,000 euros for its renovation, alongside other buildings in the diocese of Pontoise.

Economical in its construction, the chapel combines functionality and symbolism, with a sober decor centered on the Theresian spirituality. Its architecture, typical of the modern movement, makes it a significant testimony of sacred art between the two wars. The property now belongs to the municipality of Montmagny, while its exact location is listed at 242 rue d'Epinay or Place Sainte-Thérèse.
