It's known as one of America's most haunted cities – and with good reason too. Selected as the filming location by M. Night Shyamalan for his blockbuster supernatural films, such as The Sixth Sense, and home to some of the oldest relics and institutions in the country, Philadelphia enjoys a highly eerie premise.

For families and couples heading to the city this October, there is a calendar chock-a-block with spooky fun for everyone to get involved with and the Philadelphia Convention & Visitors Bureau is therefore encouraging visitors to come and explore the city's fascinating past, combined with myriad haunting events this autumn. From the 'Terror Behind The Walls' experience at the prison-turned-museum Eastern State Penitentiary to haunted historical sites, such as Fort Mifflin Battlefield, even the most steely character is bound to get a case of the jitters while exploring the United States' first world heritage city this Halloween.
