Upper choir, south side, flying buttresses
Here you can clearly see the evidence supporting the notion that the choir flyers. damaged by deformation and sheering, were demolished and rebuilt c.1500: the tracery panels have a mixture of Flamboyant and geometric motifs, the latter preserved from the original flyers. From the top down we see Flamboyant, Flamboyant, geometric, geometric, Flamboyant, geometric. The panels have been braced with iron ties. Not only were the flyers too flimsy, but they were also placed too high: Pierre Tarisel has inserted a new flyer beneath the old one, allowing him to demolish the old unit and replace it using a combination of old and new masonry elements
