Is there a website where I can find out the hours of several Paris churches?

I just googled 'Paris churches" and came up with this:
http://www.sacred-destinations.com/f...s-of-paris.htm

HOurs for what? When they are open or for services in particular?

There is a great website by the Archdiocese of Paris that has links to specific churches with hours (and websites, if they have them).
Of course, that is only for Catholic churches, but that's many of them.

www.catholique-paris.com

It may be only in French, not sure. For websites/hours click on "paroisses" at the top left side and then you can click on "Sites web" if you want indiv. churches. Or, you can click on the actual name of a church in the list by arrondisement.

You can also just click on "messes" at the top bar, and then you can click on the map for a specific arrondisement and it lists all of them by time and day.

Not sure what experience you are looking for but we have attended "The American Church in Paris" and found the service wonderful. Mostly ex-pat's. I would suggest it to anyone visiting in Paris and will be there Oct 29th.

Sorry ... I'll be more clear. I meant opening hours. I wanted to make sure that I wasn't planning on entering a church when it was closed.

Thanks, Christina. This link has many of the churches I'd planned to visit.
