Terror Behind the Walls, consistently ranked among the top haunted attractions in the nation, is located inside the massive, castle-like walls of Eastern State Penitentiary in Philadelphia, Pennsylvania. To celebrate its 2017 season of scares, Terror Behind the Walls unveils a brand-new attraction: Blood Yard.
Deep within the ruins of the prison compound, visitors discover the camp of a gruesome colony. A path marked with bones leads them deeper into the lair of the butcher, the warriors, and their ancient empress - the forgotten who now reside amongst the fragments of the lost prison. The beating of the drums becomes louder and louder, faster and faster. Finally they reach the source -- a gory site of gnawed bones and decayed flesh. The carnage sends a clear message: you could be next. Hunt or be hunted.
