Teaming up with paranormal investigator Katrina Weidman, Jack Osbourne (yes, Ozzy’s son) is delivering goosebumps in the new Travel Channel series “Portals to Hell.” The episode set to air on May 21 investigates the long and dark history of exorcisms and death at one of the most haunted mansions in the state – The Croke-Patterson Mansion in Denver, Colorado.

While there are many tales surrounding the 130-year-old mansion, from unexplained sounds of screaming babies to opening and closing of drawers to suicidal guard dogs, this place will be sure to send chills down your spine.

There’s also reports of a lack of oxygen on the stairs to the third floor – and it’s allegedly not just the altitude.

The Croke-Patterson Mansion is located at 420 East Eleventh Avenue. Situated on Quality Hill, the 12,500 square-foot mansion features a grand ballroom, nine uniquely themed bedrooms, nine bathrooms, a living room, a library, and a dining room. It’s also said to be one of the oldest still-standing residences in the city of Denver. Here’s a look at where it’s located on the map.

The building was first commissioned in 1890 by Thomas B. Croke, a merchant and plant breeder who also served in the Colorado Senate. Croke eventually sold the property in 1892 to Thomas Patterson, who represented the state in the U.S. Senate from 1901 to 1907. He was also the publisher of Rocky Mountain News. After years as serving as apartments and office spaces, the mansion was left vacant until Brian Higgins acquired it in 2011 for $565,000, according to a report from the Business Den.

As for today, the historic 1891 sandstone mansion now operates as a boutique bed and breakfast also known as the Patterson Inn. It has also been granted historic designation from the Landmark Preservation Commission, Colorado State Register of Historic Properties, and the National Register of Historic Places.
