Under a new archbishop, Henri de Sully, a more ambitious building program began. In 1181–82 King Philip Augustus II authorised construction over parts of old ramparts overlooking the city. A document from the Bishop, Henry de Sully, indicated the total reconstruction of the cathedral in 1195. The first work involved building a lower church in a space six meters deep where the old ramparts had been. This structure, with a double disambulatory, was finished in about 1200. It served as the base for the next portion, the chevet or east end, which was finished in about 1206. The work then preceded toward the west, from the apse to the choir.
