The infamous S.K. Pierce Mansion, dubbed one of the “most haunted” homes in Massachusetts, is currently on the market for $1.2 million for any potential buyers who don’t mind having permanent, undead roommates.
The house, which was built in the Second Empire style in 1875, is located at 4 West Broadway in Gardner, Massachusetts, and features nine bedrooms and three-and-a-half bathrooms. Although the mansion itself is beautiful, its dark history and alleged paranormal happenings are what draw attention to the home nowadays.
Supposedly haunted by the successful furniture manufacturer Sylvester Knowlton Pierce, his family and staff, and even 20th-century murder victims, the 7,000-square-foot mansion has been featured in TV shows like Ghost Hunters and Ghost Adventures.
“Famed for its paranormal activity and globally recognized by ghost hunters, history buffs, and thrill-seekers alike, this property is the ultimate opportunity to create a destination Airbnb, boutique B&B, or unforgettable event venue that guests will travel far and wide to experience,” the listing reads.
“Own a true piece of haunted history and turn legend into legacy!”
The History Of The S.K. Pierce Mansion
The S.K. Pierce Mansion belonged to Sylvester Knowlton Pierce, the founder of S.K. Pierce and Sons Furniture Company, which manufactured chairs. His business in Gardner did so well that he was able to have the sprawling home at 4 West Broadway built between 1873 and 1875.
Pierce hired a renowned local architectural firm, E. Boyden & Son, to design the mansion. The construction involved more than 100 workers and resulted in a grand estate which featured intricate, hand-carved woodwork throughout. It was truly a testament to Pierce's wealth and status, but almost immediately after his family moved in, tragedy struck.
Pierce's first wife, Susan, was hit with a sudden bacterial illness that quickly claimed her life, and although Pierce eventually remarried, Susan's death cast a dark shadow over the property. Then, after Sylvester Pierce died in 1888, the family fortune began to dwindle, and Pierce's youngest son, Edward, eventually converted the home into a boarding house.

During the Great Depression, the S.K. Pierce Mansion reportedly became a hotbed of gambling and prostitution. One sex worker was allegedly strangled in the boarding house's "Red Room," and she now haunts the property — along with the ghost of a man who is believed to be her killer.
However, The Gardner News noted in 2021 that there is no historical evidence to support that the home was ever used as a brothel. Then-curator Kenneth Watson also stated that the story about the murdered sex worker was not true, nor was there any record to support claims that famous figures like Norman Rockwell, Bette Davis, or Calvin Coolidge ever stayed at the home when it served as an inn in the early 20th century.
Another famous story about the S.K. Pierce Mansion stems from an incident in April 1963, when the Gardner Fire Department was called to the boarding house after occupants reported smoke pouring out of one room. Inside, a Finnish immigrant named Eino Saari was lying unconscious on a burning bed, and although the fire was extinguished and Saari was rushed to the hospital, he did not survive.
The rumor spread that Saari had spontaneously combusted, and the story stuck. That said, official records state that he had likely been smoking in bed when he fell asleep, causing the fire.
Still, these stories have contributed to countless claims of paranormal activity occurring in the house.
Alleged Paranormal Activity At The Haunted Mansion In Gardner, Massachusetts
Over the years, the S.K. Pierce Mansion has developed a reputation as a haunted house. According to the official website of the historic home, guests have reported seeing the ghosts of Sylvster K. Pierce, Susan, Edward, and a nanny named Mattie Cornwell.
Others have also claimed to see the apparition of Eino Saari, as well as other unnamed dark entities in the basement. Some of the alleged paranormal encounters include the sounds of voices and chanting, moving furniture, screens flying off windows, slamming doors, sudden temperature changes, foul odors, shadow people, and, oddly, a loud roar like a lion's, which many say is Sylvester Pierce himself, angered over the current state of his former home.

One visitor even reported that she felt a presence of some kind attempting to push her down the stairs, while another claimed they were nearly shoved out of a third-floor window.
A couple who purchased the home in 2009 was reportedly forced to sell it due to the hauntings. Rob and Allison Conti currently own the mansion, and they spent several years restoring it before opening it to the public for tours in 2022.
The Contis have now listed the home as well — though they have not mentioned if ghosts are the reason behind the sale.
