Saint-Pierre-de-Cormeilles is a town with over 600 inhabitants, particularly extensive with 1728 ha in size. It surrounds Cormeilles ¾.
The proximity of the three cities and the names of Cormeilles Saint-Pierre-de-Cormeilles and Saint-Sylvestre-de-Cormeilles suggest a common origin.
Before the Revolution of 1789, the Kingdom of France was made of parishes grouped around their church. This is the revolution which, by creating communes and departments, will transform the three parishes of St. Croix, St. Sylvester and St. Peter in three communes: Cormeilles Saint-Sylvestre-de-Cormeilles and Saint-Pierre-de-Cormeilles.
