Pier tops follow OSM (26 m gabled caps in the nave, 30 m pinnacles with gablets around the choir and chevet).","Spire (Viollet-le-Duc, rebuilt 2024): octagonal openwork stages to ~62 m, crocketed needle, cross at 96 m (OSM height); the 16 copper apostle/evangelist statues on the four roof valleys are simplified patina figures.","Transept facades: portal with gable, glazed claire-voie, ~11 m rose, steep gable with small rose, corner turrets to ~47 m on the mapped turret parts. Rose tracery is a simplified rayonnant pattern.","Inferred: chapel wall/roof heights (10.5 m mapped base, lean-to to 12.8 m), tribune roofs (21-25 m lean-to), window sizes and counts per bay (bays follow the mapped flyer positions), sacristy parts without heights kept at 8.6 m.
