Did you know, Notre Dame de Paris is French for "Our Lady of Paris"?
The Notre Dame is one of the most beautiful old churches (completed in 1345) I've seen in my life; and I've seen a lot of 12th century old churches, but seldom one this magnificent in its time.
At the top there are gargoyles surrounding the architecture overlooking the city of Paris, reminds me of Quasi Modo and his friends, silently gazing out at the ever advancing city below through the centuries.

The most famous bell in all of France (possibly Europe)
"Victor Hugo" - famous for writing/publishing The Hunchback of Notre-Dame
