Church of Notre-Dame-la-Riche
The church of Notre-Dame-la-Riche dates mainly from the 15th century, but the origins of the building are very old. Texts attest to the existence of this church dedicated to Notre-Dame-la-Pauvre as early as 920. The church has been rebuilt several times. It has been known as Notre-Dame-la-Riche since 1141. All that remains of this church is the crypt of Saint-Gatien, which is outside the plan of the present church. During the Revolution, the church was used for the manufacture of saltpetre. It was returned to worship in 1798. The first restoration of the church was carried out between 1818 and 1820. The church was restored and partially rebuilt by architect Gustave Guérin between 1860 and 1866.
