The nave and choir however had not been restored. During vespers on 11 February 1754 a great stone fell from the roof of the choir, and it was decided, before the entire body of the cathedral collapsed, to demolish all these parts and rebuild them. The demolition was carried out between 1756 and 1768, leaving only the towers and west front standing. Rebuilding began in 1787, shortly after which the French Revolution began and all work was suspended. It did not recommence until 1816, initially under the supervision of the architect Mathurin Crucy. He died in 1826; the work was continued under the local architect Louis Richelot, and finished in 1845.
