The Columbia University tunnels are a network of underground passageways that connect various parts of the campus that although largely unseen by the public eye, have become a subject of fascination, myth, and intrigue, sparking the imaginations of students and curious travelers alike. In this article, we’ll present everything there is to know about the Columbia University tunnels and tell you all you need to know in case you want to visit them.
History of the Columbia University Tunnels

The history of the Columbia University tunnels started in the early 20th century when the university decided to create an infrastructure that could make moving around the campus more efficient. Initially, the tunnels served as corridors for electrical wiring, plumbing, and other crucial infrastructure needs.
As the university continued to expand and evolve, so did the tunnel system. Over the years, additional sections were constructed to connect new parts of the campus (and new access points were added).
The tunnels of Columbia University have provided a means to house utility services, and also accommodated maintenance access to different buildings on campus, ensuring the aesthetically pleasing yet functional above-ground environment.

Layout Аnd Structure Оf Тhe Tunnel System

While specific details are not widely publicized, here is a general overview of the layout and structure of the tunnel system:
Interconnected Network
The tunnel system consists of a network of underground passageways that connect multiple buildings throughout the campus.
Access Points and Entrances
The tunnel system has various access points and entrances located in different buildings across the campus that typically lead to stairwells or doorways that provide entry into the tunnels.
Routes and Connections
The tunnels follow specific routes to connect buildings and ensure efficient navigation. They usually extend beneath roadways or walkways, allowing for uninterrupted travel between different parts of the campus.
Utility Services and Infrastructure
The tunnels house essential utility services- electrical wiring, plumbing, heating, ventilation, and air conditioning systems.
Size and Design
The tunnels vary in size and design, depending on their purpose and the specific needs of the buildings they connect. Some tunnels are wide enough to accommodate utility equipment and personnel, while others are smaller and can barely fit a couple of adults at a time.
Functions and Uses of the Tunnels

First and foremost, these tunnels house essential utility services.
Additionally, the tunnels provide a dedicated space to support various infrastructure elements such as conduits, pipes, and cables.
The tunnels also provide a convenient and discreet pathway for maintenance personnel to perform repairs, inspections, and upgrades.
In addition to their practical functions, the tunnels also serve as secure storage areas for equipment, supplies, archives, or sensitive materials.
During emergencies, the tunnels can serve as evacuation routes, enabling students, faculty, and staff to safely exit buildings and move to designated safe areas on campus.

Access And Security

The university has implemented strict measures to ensure that only authorized individuals have access to the tunnel system and not anyone can access the tunnels (although there is a workaround for that too).
To enhance security, the university has implemented various measures within the tunnel system. Surveillance cameras can be found at a few of the entries and most entry gates/doors are locked.

Myths And Legends

The Columbia University tunnels have become the subject of various myths and legends and here are a few of the most popular ones:
Secret Underground Society
One popular myth suggests the existence of a secret society or secret community that uses the tunnels to hold meetings beneath the campus and engage in mysterious activities.
Hidden Treasures and Artifacts
Another myth revolves around hidden treasures or valuable artifacts buried within the tunnels.
Ghostly Encounters
Some students and staff have shared tales of encountering ghosts or supernatural phenomena within the tunnels with stories describing unexplained sounds, flickering lights, or apparitions.
Secret Passageways and Escape Routes
A prevalent myth suggests the existence of secret passageways or escape routes within the tunnels, designed for covert purposes or emergencies.
How To Get Inside?
In the vicinity of Uris Hall, specifically on the northeast side near Sherman/Fairchild and Schermerhorn, there is a fenced-off area that extends multiple stories below ground level. Interestingly, the gates blocking this area have consistently been left unlocked, allowing access to the tunnels from underneath.
Furthermore, access to the tunnels can also be obtained from the basement of Schermerhorn. Additionally, if my recollection is correct, it is possible to access the tunnel through which communications equipment runs from Dodge to Lewison, continuing on to the Math building.
However, it is important to remember that venturing into the tunnels without proper authorization is strictly prohibited for safety and security reasons.
