Notre Dame Cathedral in Paris took over 180 years to build from 1163 to 1334. As the most iconic building in Paris, it is located on the Ile de la Cite and stands as a Gothic masterpiece on the site of a former Roman temple. Main attractions include the Crown of Thorns, towers, paintings, sculptures, gargoyles, rose windows depicting the Virgin Mary, and flying buttresses that hold up the large structure to allow more light inside.
