Considered one of the most haunted places in Ohio, Franklin Castle in Cleveland has quite the paranormal history. The Victorian-style home was originally built in the 1880s by grocer-turned-banker Hannes Tiedemann. Many of Tiedemann's close relatives died in the house, including his 15-year-old daughter, his mother, his wife, and three other of his infant children.
After Tiedemann died in 1908, it spent many years as a German cultural center and base for the German Socialist Party. However, throughout the 1960s, tales surfaced of paranormal activity within the castle walls. Visitors have claimed they've experienced electrical surges, heard crying babies, and even saw a mysterious woman emerging from black steam.
Rumors of heinous acts, like multiple murders and a mass shooting motivated by Nazi politics in the basement, have emerged. However, many of these claims are unsubstantiated. Regardless, people have claimed to see apparitions such as Tiedemann's illegitimate daughter, who is rumored to have been hanged by her father, and his mistress, who he also allegedly killed with an axe.
In early 1984, Michael DeVinko, an actor and the last husband of Judy Garland, purchased Franklin Castle. DeVinko reportedly spent close to one million dollars renovating Franklin Castle before selling. However, fires occurred over the years that damaged the home. In 2011, it only sold for a mere $260,000, down from its $350,000 selling price in 1999. The home is now reportedly vacant.
