1. Story
2. The cathedral on the Ile de la Cite, begun in 1163 and built over roughly a century. It is central to this Journey for two reasons. First, its nave is one of the earliest buildings on which flying buttresses were used at scale, and whether the original 12th-century nave had them or whether they were added in a later campaign has been argued for over a century - the fabric has been altered enough that the question is genuinely hard. Second, the fire of 15 April 2019 destroyed the 19th-century timber spire and most of the medieval oak roof frame and left the vaults locally breached, and the reconstruction that followed became an unplanned public experiment in medieval craft: the roof frame was rebuilt in oak using hand-hewn timber and traditional joints rather than in steel or laminated timber. The cathedral reopened for worship on 8 December 2024 with associated works continuing. Restoration also produced new archaeology, including 13th-century iron staples found within the masonry.

16. Evidence
17. Fire on 15 April 2019 destroyed the 19th-century spire and the medieval roof frame; the roof frame was rebuilt in oak using traditional carpentry, and the cathedral reopened for worship on 8 December 2024 with associated works continuing. V55 verification basis: no French government domain was reachable in this session; dates are stated from established record and the status of works as of August 2026 is NOT established.
18. Photoelastic model studies of Gothic structures arguing that wind loading on the high roof and clerestory, rather than vault thrust alone, was a principal design driver for flying buttresses, and that upper flyers are best explained as wind bracing. V55 verification basis: real and widely cited; not read in this session, and the argument is summarised here from its reception rather than from the text.
