The story
As you stand here in the middle of Jakubské náměstí, take a moment to look up. Before you rises the Church of St. James, a masterpiece of late Gothic architecture with a spire that pierces the Brno skyline at ninety-two meters.
It is a place of light, prayer, and history. But as the cars pass and the locals sip their coffee in the nearby cafes, there is another world existing right beneath the soles of your shoes—a world that remained completely forgotten for over two hundred years. In 2001, during a routine archaeological survey before the square was repaved, workers lifted a stone and found themselves staring into a dark, subterranean abyss.
What they discovered was staggering: the St. James Ossuary. It is the second-largest site of its kind in all of Europe, surpassed only by the famous catacombs of Paris.
Hidden in these cold, stone chambers are the remains of over fifty thousand people. As you descend the modern staircase into the crypt, the temperature drops and the sounds of the bustling city above fade into a heavy, respectful silence. This was never meant to be a macabre spectacle.
In the Middle Ages, the cemetery surrounding the church simply ran out of space. To make room for the new, the remains of the old were exhumed and moved into these cellars. Here lie victims of the Great Plague and cholera epidemics, as well as those who fell during the Swedish siege of Brno during the Thirty Years' War.
The way the bones are arranged is both haunting and strangely beautiful. Skulls and femurs are stacked with architectural precision, forming walls and pillars that reach toward the vaulted ceilings. This isn't a chaotic pile; it is a meticulously curated memorial.
You will see columns of bone that look like frozen waves and cross-shaped arrangements that remind us of the deep faith of those who lived here centuries ago. The lighting is dim and amber, casting long shadows that dance across the weathered surfaces of the bone, emphasizing the "Memento Mori"—the reminder that we are all mortal. Before you leave the square, look toward the south window of the church tower.
If you look closely, you will see a small, cheeky stone figure known as the Nehaňba, or the Indecent Little Man, who appears to be showing his bare backside to the nearby Cathedral of St. Peter and Paul. It is a classic bit of Brno humor, a wink from the past that serves as a perfect counterpoint to the gravity of the ossuary below.
Life and death, humor and solemnity, all layered together right here at St. James. As you continue your walk, remember the fifty thousand silent residents resting just a few feet below the pavement.
