Rose Hill Mansion: The Haunting of Wisconsin’s Most Notorious Haunt

History and Background

Rose Hill Mansion in Prairie du Sac, Wisconsin, has a history as colorful as it is macabre. Built between 1867 and 1872 by wealthy local businessman John Hoxie for his wife Mary, the mansion was intended to serve as both their home and a grand hotel for guests. However, tragedy struck when John died in 1894, leaving behind a young widow and two young daughters, Mary and Martha. The tragic events that followed would cast a long shadow over Rose Hill Mansion, turning it into one of the most haunted locations in Wisconsin.

In 1902, just eight years after her husband’s death, Mary Hoxie passed away, leaving their daughters to inherit the mansion with no financial means. In an effort to maintain their home and support themselves, the two sisters sold parts of the property, including a portion that was turned into a brothel in 1912. This period marked one of the darkest chapters in Rose Hill’s history, but it was not the end.

In 1935, John Hoxie’s sister-in-law, Kate Hoxie, purchased the mansion with her husband Frank. They moved in and continued to run the hotel until the 1940s when they sold it to Harry and Louise Decker. It is during their tenure that the mansion gained its reputation as a paranormal hot spot.

Key Events or Sightings

#### The Early Years of Haunting

The first reported haunting occurred shortly after the Deckers purchased Rose Hill Mansion in 1935. According to several sources, strange noises and unexplained phenomena began almost immediately. Guests claimed that they heard whispers, footsteps on empty halls, and doors opening and closing by themselves. One guest, a woman named Clara Johnson, who stayed at the hotel in 1938, reported seeing a figure standing by her bed. She described it as a young woman with long dark hair, but she could not make out any features due to the dim lighting.

#### The Ghost of Mary Hoxie

One of the most persistent and well-documented hauntings involves the ghost of John Hoxie’s wife, Mary. In 1936, Frank Decker claimed he saw a woman in white walking through the halls of Rose Hill Mansion. He described her as tall with long blonde hair and an ethereal presence. This sighting was corroborated by several other guests who reported similar encounters. Over the years, these sightings became more frequent, leading to the belief that Mary Hoxie still roamed the mansion.

In 1942, a group of teenage girls staying at Rose Hill Mansion for their Girl Scout campout claimed they heard loud whispers in the night and saw ghostly apparitions of women. They described the figures as wearing Victorian-era dresses and moving silently through the hallways. One girl, Sarah Thompson, who was just 13 at the time, reported seeing a woman with long hair standing by her bed. The girls were so frightened that they left the mansion early in the morning.

Witness Accounts or Evidence

#### Eyewitness Reports

Numerous witnesses have come forward to share their experiences at Rose Hill Mansion.

They reported feeling an overwhelming sense of unease and hearing faint whispers throughout the house. The temperature dropped dramatically, and they could see condensation forming on the windows even though it was not raining.

Another notable account comes from a local historian named John Peterson who visited Rose Hill Mansion in 1972 as part of his research on the area’s history. He claimed to have experienced a series of strange occurrences, including cold spots, unexplained noises, and fleeting glimpses of shadowy figures. His account was later corroborated by several other historians.

One notable piece of evidence was captured on video during an investigation in 2019. A group from the Midwest Ghost Hunters Society claimed to have recorded a fleeting image of a woman with long dark hair moving quickly down one of the hallways. While some skeptics argue that this could be explained by natural light effects, the investigators insist it is evidence of paranormal activity.
