This is the interior of Notre Dame cathedral. It is a huge church. Most of the people in it were tourists, but there were quite a few sitting or kneeling at the benches in the main hall. (I thought it was inappropriate for tourists to walk down the main aisle and take pictures where people were praying or just meditating.) It is a beautiful building, and one of Paris' main attractions.

I could have put a lot more photos of this on the blog.
