Laon Cathedral 

The Laon cathedral is one of the most important examples of the Gothic history in the 12th and 13th centuries.   Located in France, this cathedral has been listed among the Monuments Historiques since 1840.  Which is an honor in France given to buildings for their historical and  architectual significance .  Laon was built before the cathedrals Sems and Notre Dame and rivals their significance throughout history.
