Its on the eastern half of the Île de la Cité that Notre Dame lies. Roman catholic cathedral and seat of the Archbishop of Paris, Notre Dame is one of the first Gothic cathedrals, amongst the finest example of sacred gothic architecture, with outstanding stained glasses, stone carvings and the first flying buttress built during history. The cathedral was desecrated during the French revolution and was rendered famous with Victor Hugo's the hunchback of Notre Dame, written to raise awareness in a building which was an heritage in state of despair. In the square in front of the Cathedral lies the Point Zero, from which the distances from Paris are measured. Superstitious sayings holds that when a tourist stands there, he will come back to Paris during his life.
