At the turn of the 20th century, the plantation that was to become Frightmare Manor was just a regular estate, owned by seemingly upstanding citizen Jeremiah Lexer. Lexer, however, turned out to be one of America's earliest and Tenessee's most prolific serial killer. More than 30 corpses were unearthed throughout the property and in its marshy backwoods--and even after Lexer took his own life, mysterious deaths continued to plague the plantation.

Nowadays, Frightmare Manor draws on this horrifying history with haunted houses recently featured in Hauntworld the Magazine and named the #1 Haunted Attraction in Eastern Tennessee by Knoxville News Media. The hair-raising events sprawl across 4.5 acres that house four attractions, including the mansion and its wooded grounds. As visitors explore, spooky special effects and actors create thrills scarier than many haunted houses' ghost-shaped wall decals.
