SCARY AMERICA

A list dedicated for the horrors of American places
  1. Easter State Penitentiary, Philadelphia
    This now-defunct prison which dates to 1829, lists two options for visitors: traditional daytime yours or an evening haunted house experience. Terror behind walls, which allows guests to participate in the shenanigans- if they dare. "Those who opt in... may be grabbed, held back, sent into hidden passageways, removed from their group, and even occasionally incorporated into the show" the site says.
