Nazareth Synagogue in Paris

A Merovingian funerary basilica was built on this site around the 6th and 7th centuries and renovated in the Carolingian period. The Royal Priory of Saint-Martin-des-Champs, Cluny's third daughter, was founded in 1060 and a new building was built on this presumed site of a miracle by Saint Martin. The original plan of the choir probably inspired that of the Basilica of Saint-Denis built a few years later, the church of the Conservatory would constitute the oldest testimony of Parisian Gothic. The abbey was declared a national property in 1790 and since 1798 has housed the new Conservatory of Arts and Crafts created by Abbot Gregory in 1794, whose former abbey church, abandoned for worship, serves as an exhibition room for its museum. The complex was largely refurbished under the July Monarchy and the Second Empire, under the direction of the architect Léon Vaudoyer. The Foucault pendulum has been installed in the choir.

"Temple of the Hymen and Fidelity" in 1795, the church was returned to worship in 1802. It was restored in the first half of the 19th century (in 1823 and again in 1843). Altarpiece of the main altar by Simon Vouet and Jacques Sarrazin.

Built in 1623, the church was modified from 1828 to 1832. Its porch was rebuilt by Baltard in 1855. First chapel of the Immaculate Conception in 1623, it became the parish church of Saint Francis of Assisi in 1791, then Saint John Saint Francis in 1797. In 1970, the church was attributed to the Armenian Catholic community. His two organs are among the first made in Paris by Cavaillé-Coll and his son in 1844. Statue of Germain Pilon (16th century) depicting Saint Francis in ecstasy, and four paintings by Brother Luke (late 17th century) depicting Saint Francis.
