Origin and history

The Basilica of Saint-Thérèse-de-Lisieux, located in Normandy, was built in honour of Saint Thérèse of the Child Jesus shortly after its canonization in 1925. Inspired by the Sacred Heart of Montmartre, this neo-Byzantine monument was designed to accommodate the increasing influx of pilgrims, exceeding the capacities of the local Carmel. Its construction, begun in 1929 under the direction of architects Louis-Marie and Louis-Stanislas Cordonnier, was completed in 1954 after interruptions due to World War II.

The initial project, led by Bishop Lemonnier and Octave Germain, met with local resistance before obtaining the support of Pope Pius XI, who wanted a building "very large, very beautiful, and as soon as possible". Financed entirely by international donations, the basilica was blessed in 1937 by the future Pope Pius XII and consecrated in 1954. Its imposing architecture (104 m long, 97 m dome) and its interior decoration rich in mosaics and stained glass make it a masterpiece of 20th century religious heritage.

Ranked a historic monument in 2011, the basilica houses a crypt decorated with marbles and mosaics, an unfinished campanile (1975), and 18 altars offered by nations in homage to Saint Thérèse. His outward cross path and relics, including those of the Saint's parents (Louis and Zélie Martin, canonized in 2015), reinforce his status as a high spiritual place. Today, it symbolizes both Marian devotion and modern sacred art.

The interior mosaics, made by Pierre Gaudin, illustrate biblical scenes and the Beatitudes, while the stained glass and sculptures (like those of Robert Coin) celebrate Thérèse's life. The campanile, reduced to 55 m due to lack of funds, houses a carillon of 51 bells offered by Belgium and the Netherlands. The basilica, labeled "Twentieth Century Heritage", remains an architectural testimony of the faith and exceptional craftsmanship.

Its history also reflects the challenges of its construction: slowed down by the war, spared by the bombings of 1944 thanks to its outposted position, then restored in the 1950s. The organs, installed after the war, and the chapel of Adoration (2000) complete this ensemble, while stamps, films and broadcasts (such as Secrets of History in 2019) perpetuate its cultural fame.
