Basilica of Saint-Denis
The building where Gothic architecture was born doubles as the graveyard of nearly every French king.

Abbot Suger's choir, finished in 1144, is widely called the first fully Gothic structure — rib vaults, pointed arches, and flying buttresses that opened the walls to light. It then became the royal necropolis: French monarchs from the 10th century through Louis XVIII lie here, in a suburb most Paris visitors skip.
What to look for
- Two plain black marble slabs over Louis XVI and Marie Antoinette in the crypt — installed only in 1975, bare beside the carved Renaissance royal tombs
- Rows of recumbent stone effigies (gisants) — 16 carved in 1264 to give long-dead kings and queens new tombs
- The lopsided west façade — its north tower was dismantled after an 1846 tornado and never rebuilt
The 86m spire is being rebuilt (started March 2025, due 2029), so expect scaffolding on the west front; it's out in Saint-Denis, north of central Paris — not a walk from the tourist core.
