Halloween Nights at Eastern State Penitentiary, a bold new iteration of the organization’s famed Halloween celebration, opens September 24, 2021. Halloween Nights, from the creators of Terror Behind the Walls, is a brand-new seasonal festival of epic proportions. It transforms abandoned cellblocks and courtyards into immersive, interactive environments and activates the historic stone architecture with large-scale video projections and other special effects. The festival spans Eastern State’s entire ten-acre property, and several sections of the penitentiary complex will be open to the public for the very first time.

Guests to Halloween Nights at Eastern State Penitentiary will experience a festival-style event consisting of 15 attractions, including two haunted houses, which can be bypassed by those wanting a less scary experience. Also included will be a 3D fun house, two immersive walkthrough experiences, three live performances, four themed bars and lounges, and special effects like laser shows and large-scale video projections.

Halloween Nights at Eastern State Penitentiary is open select nights from September 24 through November 13, 2021. Ticket prices start at $34 and vary by night. Tickets are on sale now at HalloweenNights.org.
