Stewart Building, Galveston
The Stewart Mansion, nestled on the western edge of Galveston Island, is one of the area's most curious and chilling landmarks. Built in 1926 by George Sealy Jr. and originally dubbed "Isla Ranch," the Mediterranean-style estate was purchased in 1933 by influential businessman and lawyer Maco Stewart, who gave the mansion its current name. Boasting 8,200 square feet of space, the mansion once stood as a symbol of coastal grandeur, with Spanish-tiled bathrooms, a second-floor balcony, and vivid murals of pirates adorning the plastered walls. Over time, it developed a reputation not just for its architecture—but for its alleged supernatural residents.
Local lore suggests that the Stewart Mansion sits on the site of a Karankawa tribal campsite, where legends of cannibalism and bloody massacres still linger. In the early 1800s, notorious pirate Jean Lafitte allegedly attacked and slaughtered the Karankawa people on this very land—adding another layer to the property’s haunted mystique. Macabre rumors even claim that Maco Stewart buried his family in the mansion’s walls, though there’s no historical evidence to support this. Still, stories of poltergeists, whispers in the halls, and ghostly figures peering from the windows have given the mansion its enduring notoriety among ghost hunters and thrill-seekers.
Today, the mansion is undergoing a transformation. After decades of decay, the once-abandoned property is being redeveloped into private condominiums by Stonehenge Real Estate Investment Company. Whether the new residents will embrace its dark past—or bring in ghost hunters for peace of mind—remains to be seen. But one thing is certain: Stewart Mansion’s eerie legacy, steeped in pirate battles, whispered hauntings, and island folklore, will remain a memorable chapter in Galveston’s colorful and mysterious history.
