The Fence

The Fence is an iconic piece of Carnegie Mellon’s Pittsburgh campus. Serving as a student-centered space for free expression and community, The Fence has brought the CMU community together for more than 100 years. 

Governed by the Student Government Graffiti and Poster Policy, The Fence maintains specific expectations regarding painting it. Adherence to the policy helps keep the tradition of The Fence alive for future Tartans.

Concerns at The Fence

Respect for fellow students and The Fence itself is key to ensuring this time-honored tradition continues. Student Government is committed to making sure all students and student organizations can freely participate in the tradition of painting The Fence. 

The Fence has, at times, been a flashpoint for discourse and a source of conflict. The Poster Policy Arbiter (PPA) is a student employed by Student Government to intake any concerns surrounding The Fence, help identify possible solutions, and encourage open and restorative dialogue among impacted students. By informing Student Government about possible violations of the Poster Policy or instances of conflict at The Fence, CMU community members help us to keep painting The Fence a positive experience for all.

Concerns about The Fence can be reported to the Poster Policy Arbiter and Student Government through one of the following methods:

  • Email (not anonymous): You can report incidents directly by emailing us. The Poster Policy Arbiter will follow up with further communication. 
  • [coming soon!] Intake Form (anonymous): If you prefer to remain anonymous, please use our Intake Form to report any incidents. While your identity will not be recorded to ensure privacy, please note that anonymity will limit the potential for restorative dialogue. However, follow-up may still be possible as deemed appropriate by the PPA.

History of The Fence

How It Started

Did you know that The Fence was actually not a meeting place for Carnegie Tech men and Maggie Mo women? The history of The Fence is often shrouded in misinformation. After university archives and student research, the earliest documented reference to the idea of “a fence” was in 1913. However, with major world events and ebbing interest, the building of The Fence was pushed to 1923 when the class of 1923 built what they referred to as the Senior Fence. Originally, The Fence was built for seniors, by seniors.

Reinforcing The Fence

During the days of the Senior Fence, the main tradition was for seniors to sit at the fence and celebrate their time on campus; non-seniors would be reprimanded for attempting to do so. However, that tradition slowly faded away, giving way to the tradition we know and love today – painting The Fence. Though there is not a specific year in which our tradition started, by the 1960s the tradition was in full-swing.

After many decades (and layers of paint), in 1989, the west end of the Fence collapsed and was replaced with pressure-treated lumber and concrete. In 1993, the east end of The Fence followed suit. While the original Senior Fence may no longer exist, today we have The Fence, not just for seniors, but for all students at Carnegie Mellon University.

The Tradition Continues

Here are some key moments of history memorialized in the layers of The Fence:

1974

The Fence is said to have been painted when President Nixon resigned

1980

The Fence was painted with “Imagine” lyrics as a memorial to John Lennon.

2001

On 9/11, The Fence was painted in remembrance of the victims. The Fence doubled as a gathering location for a candlelight vigil later the same day.

2008

After the passing of CMU Professor Randy Pausch,who gave and wrote "The Last Lecture”, The Fence was painted in his honor. 

2011

After first-year art students damaged The Fence with a hacksaw, students rallied around its restoration. “Operation Heal the Fence”, a student-coordinated event, “attracted hundreds of students to the Cut that night to reclaim and repaint the Fence”.

2020

During the COVID-19 pandemic, The Fence was painted with a very relatable “CYA on Zoom.” 

2020

When someone changed the “Black Lives Matter” message to “All Lives Matter,” students quickly gathered to repaint The Fence to its original message.

Generations of students have used The Fence to advertise, celebrate, and remember major events in our individual and collective lives. In recent years, this has included an increase in the use of the Fence as a platform for student expression.

In 2024, the Student Government, with help of university leadership, helped cement some of the core tenets of our Fence in the space bordering The Fence. These values include our student-centered foundation, our belief in free expression, respect for The Fence and our community, and the Student Government’s commitment to protect these values.
