of Paris. It is widely considered to be the finest example of Gothic architecture in Europe.

Work on the cathedral was begun in 1163 but the building was not completed until 1345

and even then work continued. A technological marvel of its time, the cathedral incorporates

a number of different styles, reflecting the input of many different architects during

its construction. The striking flying buttresses of the exterior were not part of the original

design but were added when the thin walls grew taller and showed signs of bowing outwards

and cracking.

The naturalist stained glass windows are stunning to view from the interior and offer a striking

contrast to earlier Romanesque architecture.

It is not believed that a hunch back ever rang the 5 bells of Notre Dame, however the

great bourbon bell in the South Tower was rung to announce the liberation of Paris from

Nazi occupation.
