Laon is one of the most important and stylistically unified examples of early Gothic architecture. The present Laon Cathedral dates from the 12th and early 13th centuries, an early example of the Gothic style that originated in northern France. It was built half a century after the erection of the Basilica of Saint-Denis, which originated the Gothic style.
