Lovely church and free to go in (love that) it was a good place to look around and there were even nuns singing beautiful. Only downside is that there are the most disgusting people at the entrance gates and as you walk up who will try to sell you crap. They are very aggressive and will try to touch you, one even tried to trip me over, I was so upset and scarred. Really mared the whole experience. I think the Church should have control of the gardens or the police should be allowed to monitor the park for safety. My advice is to come in from the back way via monmartte (sp) if you can, lovely part of Paris.
