Church of Saint-Leu-Saint-Gilles

The cathedral, whose construction was decided by Louis XV, replaced the old cult building of the city which stood on the banks of the Seine and became too narrow. In 1966, it was raised to the dignity of a cathedral while waiting for the construction of the one in Créteil. Since then, it has retained the title of cathedral but not its function. Even today, it still retains traces of its originality: on the pediment of the south façade of the chevet, it bears the republican motto Liberté-Egalité-Fraternité (Liberty-Equality-Fraternity). The bell tower is abnormally low because King Louis XV did not like the sound of the bells. In the 20th century, a carillon was added to the bell tower playing the "Marseillaise" because Rouget de l'Isle was buried in Choisy. Louis XV and the Marquise de Pompadour attended mass from a small oratory with a tribune on the first floor of the choir.

The construction of the Church of St. Dove dates back to the middle Middle Ages. The original nave was built between the 10th and 12th centuries before being demolished in the 13th or 14th century. The choir and the bell tower date from the 13th century. The framework covered with panelling dates back to the 17th century.

Built between the 12th and 14th centuries, it was classified as a historical monument in 1862. Saint-Germain Church, a historic monument located in the town centre, underwent major works as soon as its construction was completed. Whether due to storms or natural aging, renovations are undertaken regularly. Built over two centuries, from 1150 to 1280, this church presents many architectural styles: late Romanesque for the original bell tower, Gothic for the construction of the current vessels, radiant Gothic for the choir.
