SPRING CITY — Looking for a frightening haunted attraction with a chilling past?

Pennhurst has opened its gates for its fourth-annual Halloween season. Open to all ages, the haunted house type events are held Thursdays through Sundays until Nov. 4.

Held on the campus of the abandoned Pennhurst State School in Spring City, the location is spooky. Dozens of ominously dark and dilapidated buildings provide the locale and backdrop for a Halloween haunted house. The campus sits on roughly 100 acres and there are 25 buildings. The buildings are interconnected by over 1000 feet of underground tunnels, which also serve as a setting for the haunted house activities.
