Saint-Pierre de Montmartre () is the second oldest surviving church in Paris, after the Abbey of Saint-Germain-des-Pres. It is one of the two main churches on Montmartre, the other being the more famous 19th-century Sacré-Cœur Basilica, just above it. Saint-Pierre de Montmartre, begun in 1133, was the church of the prestigious Montmartre Abbey, destroyed in the French Revolution.Dumoulin, Ardisson, Maingard and Antonello, Églises de Paris (2010), pp 180-183 Read more on Wikipedia
