Overview of Terror

The massive Eastern State Penitentiary — a gothic, castle-like structure in Philadelphia’s Fairmount neighborhood — is also home to one of the nation’s largest and most ambitious and top-rated haunted attractions, Terror Behind the Walls.

Once the most famous and expensive prison in the country, Eastern State Penitentiary now stands as a living ruin with long empty cell blocks and remnants of the past. The frightening setting and professional scares make Terror Behind the Walls one of the country’s top-ranked haunted attractions.

Designed to be high-startle, Terror Behind the Walls includes Hollywood-quality special effects and lighting, digital sound, animatronic creatures and custom props. Over 200 performers are needed for six separate attractions in the 11-acre complex.

Frightening Attractions

Terror Behind the Walls is more frightening than ever. Expanding on a terrifying option introduced in 2013, visitors can decide if they want to be fully immersed in the action by marking themselves to be potentially grabbed, held back, taken into hidden passageways and maybe even become part of the scares.

Venture into the Machine Shop, the most interactive attraction ever devised for Terror Behind the Walls. Visitors will be led deep into the cellblocks into a space never before open to the public. Expect industrial nightmares and unique one-on-one experiences that will surely stick with you.

Additional attractions at Terror Behind the Walls include Lock Down, a riot inside Cellblock 12, said to be the most haunted spot inside the penitentiary; Detrius, a walk through an original 1800s cellblock and the overgrown prison greenhouse; Infirmary, a frightening look into the world of prison medical treatment; The Experiment, a disturbing, 3-D fun house; and Night Watch, a pitch-black, disorienting trip through the narrow hallways of the penitentiary.

Two Groundbreaking New Attractions In 2015

Each year, the creators of Terror Behind the Walls pull out all the stops for a thrilling Halloween experience. For the attraction’s 25th anniversary, two brand-new attractions will be unveiled to complement four returning attractions, giving everyone — even repeat visitors — a surprising and haunting show.

Inside Quarantine: 4D, visitors will be immersed in the experience of being exposed to an infectious outbreak — with symptoms like hallucinations, distorted depth perception and other mind-altering effects.

The final attraction of the haunted house this year brings the second new attraction: Break Out, a prison-break style adventure with inmates trying to escape every way imaginable.
