Laon Cathedral

Laon Cathedral (Cathédrale Notre-Dame de Laon) is a medieval cathedral in Laon, Aisne, in northern France, and one of the early major examples of Gothic architecture in the region. Construction began in the late 12th century and the building is noted for its intact medieval fabric and prominent towered silhouette.

The building is known for its monumental west front with twin towers and additional towers at the transept, large rose windows, and an interior that displays ribbed vaults and pointed arches typical of early Gothic design. The cathedral’s exterior sculpture and tower groupings are among the main highlights for visitors interested in medieval architecture.

Construction began in the late 12th century and continued into the 13th century, with successive campaigns shaping the present form. The cathedral has undergone repairs and conservation over later centuries to address structural and decay issues.

The cathedral sits within the old hilltop town of Laon in the Hauts-de-France region, overlooking the Picardy plain. Laon is roughly north of Paris and the cathedral occupies a central position in the town’s historic core.
