An abandoned Salt Lake City factory has been named one of the best haunted houses in the U.S.
Formerly a cement factory known as Portland Cement Works, the facility carries an eerie history.
It also endured several accidents and eventually closed.
The first fatality occurred in 1900 when a worker was pulled into a revolving shaft.
With no safety measures put in place, workers at the factory continued to be killed.
The site reopened as a haunted house in 2011 and is now known as Fear Factory.
The attraction consists of six buildings up to six stories high and two underground passages.
