The dominant religion in France is Catholic, at least nominally, with 80 % of the population. 5-10% are Muslim; 2% Protestant; 1% Jewish. There are also a good number of people with no religious affiliation. Since 1905, and the separation of church and state, most Catholic church buildings are government property. Support of individual churches varies greatly from declining to growing. French Protestant churches are called “temples.”
If you would like to attend a mass or service, here are a few ideas (please follow the links for more information):

A more modern, welcoming Catholic service might be at St Merri (76 rue de la Verrerie – 75004)
