I want to know the answer to the following question:
What style of nave was left unaltered during this portion of the reconstruction of Saint Denis?
All the background I'm provided with is that "To achieve his aims, his masons drew on the several new features which evolved or had been introduced to Romanesque architecture, the pointed arch, the ribbed vault, the ambulatory with radiating chapels, the clustered columns supporting ribs springing in different directions and the flying buttresses which enabled the insertion of large clerestory windows.". Is that enough to answer the question?
Answer: no
