The History
The Congdon Legacy
The story of Glensheen Mansion begins with Chester Adgate Congdon, a lawyer, investor, and philanthropist. In the early 20th century, as Duluth’s wealth skyrocketed thanks to mining and shipping industries, Chester rose to prominence. He commissioned the construction of Glensheen between 1905 and 1908—a 39-room mansion built on a stunning 12-acre estate hugging Lake Superior. The mansion was designed by Clarence H. Johnston, a prominent Minnesota architect, and decorated with the finest materials and craftsmanship available at the time.
Chester and his wife Clara raised seven children in the mansion, enjoying a life of privilege and high society. The Congdons became known for their contributions to Minnesota’s educational and conservation efforts. Glensheen was more than a showpiece; it was the backdrop for a family deeply involved in shaping regional history.
A Gilded Age Time Capsule
Preserved meticulously over the decades, Glensheen serves as a time capsule of early 20th-century life—featuring original furniture, textiles, fixtures, and even personal items from the Congdon family. Unlike many historic homes where only portions remain authentic, Glensheen’s interiors remain largely untouched, offering a rare and immersive window into the lifestyle of America’s elite during the early 1900s.
One of the most impressive aspects of the mansion is its self-sufficiency. It was equipped with cutting-edge technology for its time, including a central vacuum system, intercoms, and a coal-fired heating plant. Designed to be both beautiful and functional, Glensheen stands today as Minnesota’s most visited historic home, inviting thousands to walk its grand halls each year.
The Infamous Tragedy
Despite the beauty and success associated with the Congdon legacy, Glensheen Mansion holds a significantly darker chapter etched into its walls. In 1977, a brutal double homicide shocked the nation when heiress Elisabeth Congdon and her night nurse, Velma Pietila, were found murdered inside the mansion. Elisabeth was smothered in her bed, while Velma was bludgeoned with a candlestick. Suspicion quickly fell upon Elisabeth’s adopted daughter, Marjorie Congdon LeRoy Caldwell, and her second husband, Roger Caldwell.
Roger was convicted of the murders, though his conviction was later overturned, and he eventually died by suicide. Marjorie, though never convicted for the Glensheen murders, went on to be linked to numerous criminal cases involving arson and insurance fraud. To this day, the murders remain a chilling part of Glensheen’s narrative, feeding into its ghost stories and mystique.
The Haunt
The Residual Energy
With all its elegance, it’s nearly impossible to ignore the whispers of the past that seem to linger in the glistening hallways and silent sitting rooms of Glensheen Mansion. According to staff and visitors, certain areas of the mansion ooze an inexplicable heaviness, especially near the bedrooms and on the grand staircase—a site central to the events in 1977.
Residual hauntings are often described at Glensheen, where emotional echoes of past trauma play out like a recording. Tour guides have reported cold spots in rooms that should be warm, lights flickering without cause, and the distinct sensation of being watched. These are most commonly experienced in Elisabeth Congdon’s bedroom, where paranormal investigators have reported sudden EMF spikes and disembodied whispers caught on digital recorders during EVP sessions.
Ghostly Sightings
Though the mansion itself maintains a policy of discretion when it comes to paranormal claims—likely out of respect for the victims and their descendants—visitors and ghost hunters have kept the tales alive. Apparitions of a woman in period clothing have been spotted near the upper floor windows, and some guests have reported the feeling of icy hands brushing against them on the main staircase.
In the basement, which once housed staff quarters and utility rooms, investigators describe particularly intense energy. Shadows darting along the walls, knocks with no origin, and items subtly shifting are frequently recounted. Paranormal equipment has recorded unexplained temperature drops and audible anomalies, supporting the mansion’s haunted reputation.
The Unexplainable Phenomena
Paranormal teams that have visited Glensheen speak of its “living silence”—an almost breathing quietness, like the house itself is waiting for something. Some psychics feel a multiplicity of energies throughout the mansion: a dominant female presence on the second floor, a childlike energy near the sunroom, and a morose aura downstairs in the linen closet. The theory among investigators is that Glensheen serves as a kind of emotional echo chamber, collecting and reflecting the triumphs and tragedies that have unfolded within its walls.
Some paranormal fans point out that the location near water—Lake Superior—is commonly associated with increased spiritual activity. Water is believed to act as a conduit for energies, adding yet another layer to Glensheen’s haunted lore. Stir in Minnesota’s long winters and the mansion’s rich emotional history, and you have the perfect recipe for supernatural activity.
