Notre-Dame: Notre-Dame looms large over the Place de Parvis, on the Isle de la Cité, and is the most enduring symbol of Paris. Built between 1163 and 1345 the Cathedral is considered one of the of the world’s Gothic masterpieces. The massive interior can seat 6,000 and it is dominated by three spectacular and enormous rose windows and a vast 7,800-pipe organ. The 387-step climb to the top of the towers is worth the effort for the panoramic view of the city and the close-up views of the famous gargoyles. The tower also holds the great bell that was rung by Quasimodo, the fictional hunchback. Opposite the North door is a museum that displays the Cathedral’s history, while under the square in front of the Cathedral is the crypt that houses Notre-Dame’s archaeological museum.
