The Eastern Faubourgs
10e, 11e, 19e and 20e arrondissements · ten churches · 19 recorded visits

To the north and east of the center, the tenth, eleventh, nineteenth and twentieth arrondissements hold ten churches in the record.
Between them they cover a long span of the city’s growth. Saint-Laurent was founded outside the walls of Paris at the end of the fifth century, and its present church dates from the fifteenth. Saint-Germain-de-Charonne keeps the look of a village church, surrounded by its old cemetery. Saint-Vincent-de-Paul, Notre-Dame-de-la-Croix and Notre-Dame-du-Perpétuel-Secours were built in the nineteenth century for quarters whose population was growing fast, and Saint-Jean-Bosco, blessed in 1937, is an Art Deco church that has been little altered since.
Saint-Ambroise has six recorded visits, from March 2019 to March 2026, the most in this section; each of the others has one or two.
