Notre Dame is a beautiful example of Gothic Architecture. I had no idea that 50,00 people visit daily, there must be some amazing grounds keepers. Do you know what type of material the floor is made of to withstand 2 million people worth of traffic annually?
It is amazing to learn that the church took a century to build. Also, it is amazing that after the French revolution it was rebuilt and preserved to its original integrity.

I agree that the Notre Dame should be preserved and that it serves as great inspiration to architect, religion, and the general public.
