In the heart of the historic city the Notre Dame Cathedral has grown over centuries and survived Viking Invasion and Allied Bombing in 1944.
A metalwork spire added in 1877 made the Cathedral in the tallest in the world for a brief time, and it is still the highest in France.
Also overhead, amongst fine Normandy style half-timber architecture is the Gros Horloge. In operation from the 14th Century until 1928 without stopping once, calculated to be more than 5 million hours.
