Breathtakingly beautiful interior. Its an absolute must visit for both locals and tourists.
Take a tour! I only took the 20 minute one, but now I wish I had taken the 60 min one. as i don't speak french, i took the english tour. my tour guide was wonderful. very knowledgeable, open to questions, english was impeccable, he had photos to show us, and was funny. i definitely learned more intriguing tidbits than I wouldve if i simply wandered around.
theres two tours. a 20 min one thats included in the $5 entrance fee, and a 60 min one that ups the entrance fee to $10. which as entrance fees go, is pretty darn inexpensive.
no food or drinks guys! i shoudlve known better but i had to finish my coffee before i could enter. (=
