Why it’s cool

These underground passages offer a meticulously crafted surrogate for the Holy Land, built over a century ago to provide a local pilgrimage site for those unable to cross the Atlantic.

A narrow, dimly lit stone corridor within the Catacombs of Washington, D.C., featuring arched niches carved into the walls.

Beneath the Franciscan Monastery of the Holy Land, the order's American home, lies a shadowy network of tunnels that feels like a portal to ancient Italy. While the humid air and dim lighting suggest a site millennia old, this subterranean world is actually a clever architectural tribute designed to bring the experience of Roman and Middle Eastern shrines to the United States.

Why It Stands Out

At the turn of the 20th century, Franciscan monks commissioned Roman architect Aristides Leonori to design a miniature version of the Roman catacombs. Using precise measurements and photographs from Italy, Leonori drafted a complex that captured the essence of the originals.

This focus on spiritual architecture is also seen at the Cave of Kelpius. Unlike the tombs in Rome that were carved into volcanic rock, these D.C. passages were cast from aggregate cement.

The complex consists of three distinct arcades representing different eras of Christian history. While most of the wall graves are symbolic recreations, the site holds one profound exception: the skeletal remains of a child martyr.

Estimated to be around seven or eight years old, the child is believed to have lived in the second century. They were brought here in 1929 from Rome's Catacomb of St.

Callistus. Above ground, the site continues its theme of replication with meticulously crafted versions of the tomb of Jesus and various Old World grottos, allowing visitors to experience a condensed global pilgrimage in a single afternoon.

Before You Go

Access to this underground labyrinth is found near the monastery’s main altar. The experience is significantly smaller than the sprawling hundreds of miles found beneath Rome, but it carries an official endorsement from the Pope.

The monastery staff provides guided walks through the three interconnected sections, explaining the historical and spiritual significance of the architecture and the various chapels. Another subterranean site in the city is The Dupont Underground.

Questions worth answering

How do we get into the tunnels?

Find the monastery's main altar to locate the entry point. The staff leads walks through three linked sections between 10 am and 3 pm from Wednesday to Friday.

Is there anything authentic down there or is it all a tribute?

Most of the wall graves are symbolic, but the skeletal remains of a child martyr are the real thing. This individual lived during the second century and was moved here from Rome in 1929.

What is the general feeling of the space?

It has a historic vibe that mimics ancient Italy through dim lighting and humid air. While the Roman originals were carved from volcanic rock, these passages were built using aggregate cement.

When can we actually walk through the tunnels?

The monastery staff leads walks through the three interconnected arcades between 10 am and 3 pm from Wednesday to Friday. You'll find the entrance to this underground labyrinth near the main altar.

Catacombs of Washington, D.C.

Beneath Washington, D.C., a dimly lit web of passages weaves throughout row after row of eerie wall graves, recalling early Christian burials in the catacombs of ancient Rome. The subterranean complex is located underneath the Franciscan Monastery of the Holy Land in America, with a Dan Brown-style entrance near the main altar and the bones of a boy martyr inside.

However, the Catacombs of Washington, D.C., aren’t quite as ancient as the name would suggest, and all but one of the graves are totally fake. They were built at the turn of the 20th century by a well meaning group of Franciscan monks who wanted to create a facsimile of the Holy Land for North Americans who couldn’t afford the trip overseas.

These catacombs do have an official Papal endorsement and contain one very real skeleton of what looks to be a seven or eight-year-old child. Legend holds that the bones belong to a martyr from the second century and made their way to D.C. from the Catacomb of St.

Callistus in 1929. Above the catacombs the Franciscans also brought together a sort of spiritual amusement park, complete with replicas of the tomb of Jesus and numerous other altars, chapels, and grottos from the Old World.

Visitors can complete a veritable world tour of Roman and Middle Eastern religious shrines in a single afternoon. A Roman architect named Aristides Leonori produced the design for a mini-catacomb based on measurements and photographs of the originals in Italy.

Three architecturally distinct sections represent various chapters from early Christian lore. Unlike the Roman originals, which were scraped from the earth and soft rock by hand two millennia ago, the D.C. catacombs were cast from aggregate cement and come in at a spry 120 years of age.

They’re also much smaller in scale: essentially three interconnected arcades, as opposed to the hundreds of miles that stretch beneath Rome.
