 Noyon Cathedral saw the earliest completion of a rebuilding of an entire French cathedral in the new style from 1150 to 1231.While using all those features that came to be known as Gothic, including pointed arches, flying buttresses and ribbed vaulting, the builders continued to employ many of the features and much of the character of Romanesque architecture including round-headed arch throughout the building, varying the shape to pointed where it was functionally practical to do so.At Saint-Denis, Sens Cathedral, Noyon Cathedral, Notre-Dame de Paris, and at the east end of Canterbury Cathedral, simple cylindrical columns predominate over the Gothic forms of clustered columns and shafted piers.
