I had quite a lovely experience in the Cathedral of Notre-Dame. The first thing I did was climb the stairs to the bell tower and enjoy some wonderful views of Paris. The stairs were killer! It gave me an insight though on the theory of the Tower of Babel, which an ancient civilization built in attempts of building a tower that would get them to heaven. The must have realized that climbing enough stairs is a quick cause of death, and that's how they get to heaven! In Notre-Dame there were 422 stairs to get to the bell tower. Definitely hard after a long day of walking!!
On my way out, I couldn't help but take a few more pictures of the beautiful building!
