Crypts, Catacombs & Ossuaries: A Spooky Season Journey Through Europe’s Sacred Shadows

Now, let’s be honest: there’s no way I can cover everything in one blog post. But consider this your appetizer—a taste of the macabre that might just inspire your next journey into the depths.

🕳️ Catacombs: Underground Cities of the Dead

Catacombs are found throughout Europe, really the world, but like I said we are sticking to Europe—probably in cities you’ve visited without realizing what lies beneath. The term catacomb originates from San Sebastiano ad Catacumbas along the Appian Way in Rome. The Latin ad catacumbas means “at the hollows” or “at the quarry.”

One of the most iconic examples? The Paris Catacombs (Les Catacombes de Paris). In 1786, Paris faced a crisis: overflowing cemeteries and flooded basements filled with corpse water. The city’s solution was both practical and macabre—repurposing abandoned limestone quarries beneath the streets. By 1860, over 6 million bodies had been transferred into this subterranean labyrinth. Though the tunnels stretch almost 200 miles, only a small portion is open to the public. The rest? Known as the Forbidden Catacombs, they’re illegal to enter. These tunnels are so notorious that the Paris police have a special unit trained to rescue those who dare to explore and become lost in the labyrinth. It’s a place where history, mystery, and mortality converge in the most haunting way.

Catacombs weren’t just practical, they were spiritual. In Rome, early Christians used them not only for burial but also for worship. Originally built by Jewish communities, these underground sanctuaries became safe havens during times of persecution. Today, more than 60 catacombs lie beneath Rome, some adorned with frescoes, relics, and inscriptions, though many areas remain closed to the public, you will find quite a few you can enjoy.

🏛️ Crypts: Sacred Chambers Beneath the Church

The Capuchin Catacombs of Palermo blur the line between catacomb and crypt. Originally a mass grave for friars in 1534, the site evolved when 45 naturally mummified bodies of some of their friars were discovered in 1597. Rather than rebury them, the friars chose to display and venerate them. By 1783, the crypt was open for laymen to be buried. And though closed for burials in 1880 there have been two exceptions one in 1920 the body of a two year old little girl, Rosalia Lombardo, known as the “world’s most beautiful mummy.”

So, what makes a crypt different? A crypt is a stone chamber beneath a church or religious building, used to house tombs, relics, or sacred artifacts, often reserved for clergy or nobility. The Capuchin site skirts both definitions—part crypt, part catacomb.

Another iconic crypt is beneath St. Peter’s Basilica in Vatican City. Known as the Vatican Grottoes, this sacred space was expanded in the 17th century and eventually led to the discovery of St. Peter’s tomb. Today, it holds the remains of several popes and is a place of pilgrimage and reverence.

Many medieval abbeys and churches across Europe have crypts—some still in use. St. Paul’s Cathedral in London continues to inter the ashes of distinguished Britons. The Royal Crypt at El Escorial in Madrid remains the burial site of Spanish monarchs, with recent interments in the 21st century.

💀 Ossuaries: Artful Arrangements of the Dead

Often mistaken for catacombs, ossuaries are not burial sites but bone repositories—places where remains are stored after decomposition. They’re more about commemoration than mourning.

The Paris Catacombs contain one of the world’s most famous ossuaries. Bones once piled loosely, but later arranged into walls in an artistic pattern, with large bones forming the structure of the wall and smaller fragments piled behind.

For something more obscure, there is the Dingolfing Ossuary in Germany. Built in the 17th century, it features over 60 skulls, each inscribed with elegant calligraphy of patterns and dates and surrounded by paintings of death and resurrection.

Then there’s the haunting Chapel of Bones in Évora, Portugal. In the 16th century, faced with an overcrowded cemetery, the Church of St. Francis chose to display the bones of those they exhumed instead of reburying them. Thousands of bones line the walls and pillars, and above the entrance reads the chilling message:

“Nós ossos que aqui estamos, pelos vossos esperamos”
(“We bones, are here, waiting for yours.”)

Finally, we journey to Niš, Serbia, home of the Skull Tower. Built in 1809 by the Ottoman Empire after the Battle of Čegar, this 15-foot monument was embedded with the skulls of Serbian rebels—a stark reminder of war’s brutality. Only 58 of the original 952 skulls remain, now protected as a Cultural Monument.
