Why was the ossuary created?

Authorities established the ossuary to alleviate severe cemetery overcrowding and address structural failures caused by mass graves.

What was the original purpose of the underground tunnels?

The subterranean passages were excavated as limestone quarries to supply building material for the city.

Which cemetery collapse accelerated the relocation of remains?

Structural collapses at the cemetery of Saints Innocents forced the closure of the burial ground and prompted the transfer of bones.

Which organization was founded to inspect the underground quarries?

The Inspection Générale des Carrières was created to investigate and consolidate undermined ground after surface collapses.

From where does the ossuary network extend?

The underground ossuary extends southward from the site of the former Barrière d'Enfer city gate.

Über den Ort

Paris rests above a vast network of subterranean limestone quarries converted into municipal ossuaries to relieve overflowing city graveyards.

The galleries originated as suburban quarries extracting Lutetian limestone to build the city above. Haphazard horizontal extraction left uncharted voids beneath the surface. As municipal borders expanded across the Left Bank, urban districts grew directly over these abandoned workings. Structural collapses prompted the crown to establish the General Inspection of Mines to consolidate the fragile underground network.

Urban burial grounds created an acute sanitary crisis in the historic core. The central Saints Innocents cemetery accumulated massive layers of remains alongside the central market until an adjacent cellar wall collapsed under the weight of a mass grave. Authorities banned city burials and converted the reinforced southern quarry tunnels into an ossuary. Nightly processions moved bones across the river to relieve urban churchyards.
