Beauvais Cathedral (French: Cathédrale Saint-Pierre de Beauvais) is an incomplete cathedral located in Beauvais, in northern France. It is, in some respects, the most daring achievement of Gothic architecture, and consists only of a transept (sixteenth-century) and choir, with apse and seven polygonal apsidal chapels (thirteenth century), which are reached by an ambulatory. The small Romanesque church of the tenth century, known as the Basse Œuvre, much restored, still occupies the site destined for the nave.

In the race to build the tallest cathedral in the 13th century, the builders of Saint-Pierre de Beauvais pushed the technology to the limits. Even though the structure was to be taller, the buttresses were made thinner in order to pass maximum light into the cathedral. In 1284, only twelve years after completion, part of the choir vault collapsed, along with a few flying buttresses. It is now believed that the collapse was caused by resonant vibrations caused by high winds.

After the collapse, lateral iron supports were installed between the flying buttresses. In the 1960s, the tie rods were removed; the thinking was that they were disgraceful and unnecessary. However, the oscillations created by the wind became amplified, and the choir partially disassociated itself from the transept. Subsequently, the tie rods were reinstalled, but this time with rods made of steel. Since steel is less supple than iron, the structure became more rigid, possibly causing additional fissures.

However, the choir here has always been wholeheartedly admired: Eugène Viollet-le-Duc called the Beauvais choir "the Parthenon of French Gothic." (http://en.wikipedia.org/wiki/Beauvais_Cathedral)
