While walking around Paris for the last month, I’ve became fascinated by the highly fossiliferous limestone that comprises so many of its iconic structures. At one point I thought, Hmm… The City of Light is built with materials of death. I had no idea how much farther that thought would take me.
Without abundant death we wouldn’t have asphalt, concrete, marble, travertine, chert, oil, gas, coal, asphalt, limestone, dolomite, and countless other requirements of civilization. So, given the unusual abundance of limestone in use here, I wondered where it came from. Naturally, from my 21st-century perspective, I assumed that all of it had been quarried in some other place: hills outside of town, perhaps. Lutetian limestone, it’s called, and it’s a relatively new rock: only a few dozen million years old. Younger than dinosaurs. It’s also known as “Paris stone”, and has become quite the fashion item lately.) What I hadn’t figured was that nearly all of this building stone, for many centuries, was extracted from beneath Paris itself: a sum large enough to build a Great Pyramid.
I didn’t learn any of that until we visited the Catacombs two days ago.
The Catacombs are bone banks called ossuaries. They occupy abandoned quarries beneath Paris and contain the remains of more than six million people. Many of the deceased were likely the same men (and women? probably) who carved out the quarries, mostly in the first several centuries of the last millennium. It must have been quite a project since these withdrew enough rock to assemble Notre Dame, thousands of other churches large and small, bridges, city walls, stone lining for the Seine, and homes—and left beneath the streets of Paris more than 300 kilometers (100 miles) of tunnels, including rooms and vaults that together comprise a vast man-made cave system. Top to bottom, a vertical cross-section of Paris looks like this:
- Surface — streets, buildings, parks
- Metro tunnels
- Sewers
- Quarries
Fossils are bones of stone, I explained to my kid. And limestones are stones of bone. Here in the Catacombs, along hallways that go on and on and on and on, the bones of dead Parisians are assembled into walls, with an artistry that makes one wonder what was going on in the heads of the masons, since they are artfully assembled from femurs and skulls. The femurs are stacked and interlocked, with the knee knuckles outward, course after course stacked to form a pattern like stitches in cloth. These are interrupted by horizontal lines of skulls, and usually topped with a final row: a crowning course of human heads—no concrete, grout, or other adhesive material anywhere. Here and there some arm bones might fill a gap, but femurs and skulls are the preferred structural material. Behind these walls lie tossed the rest of the bones: remains of remains.
The masons were priests. The bones were gathered from the city’s cemeteries, which had become rotten with an abundance of corpses as the end of the 18th century approached. That’s when it was decided to move the bones down into deeper graves. The quarries were empty, so the space was repurposed as catacombs. The project worked along stretches of a few years each, from the late 1700s to the middle 1800s, as one cemetery after another was emptied and its occupants relocated. The priests, whose jobs already required exceptional respect for the dead, were conscripted for the work.
The pictures in my collection (e.g. the one above) aren’t the best I’ve taken. Most of the light was provided by cell phones or the respectfully dim illumination of the catacombs’ operators. If you wish to know more (and I recommend it), here is a pile of fascinating links:

Since one walks through the quarry tunnels in the company of guides and other people, the place is less creepy than you might think. Endless aisles of bones also tend to make all of it ordinary. Yet one wonders: Is this skull Jacques Hébert‘s? George-Jacques Danton‘s? Charlotte Corday‘s? Madame du Barry‘s? All lost their heads to the guillotine and were planted in cemeteries later emptied and relocated here, where their skulls are equally ordinary and anonymous: fully respected, but still just building material.
A lesson: different as we look and sound in life, we are remarkably alike in death. Skulls tend to all look the same. So do other bones. One might pause to think, These were babies once. Children. Teenagers. They grew up, mated, worked, and produced more babies who grew up, got work done, and died. What they’ve left is no different than what everyone else leaves. (Unless, of course, they are turned to dust or ash by other circumstantial or funerary means.)
What makes us animals is that we eat other living things. (We need their carbon.) We live on things that lived. And we build with them too. Death supplies us. In turn, we supply death—and lessons such as those on this page.
What makes us special, for the time we live and for the legacies we leave, is who we are and what we do when we’re alive. Life is for the living. And so, it turns out, is death.
