The history
Duluth's haunted ground is a Lake Superior port in two buildings and one ship, all three documented on their own operators' pages. In Canal Park, the Duluth Ghost Tours walk starts at the Lakewalk by the Marine Museum, in a district its operator's local-haunts page describes as a historic red-light district whose buildings still stand, converted to restaurants and shops. Moored in the same district, under the Aerial Lift Bridge, is the William A. Irvin: launched November 21, 1937 at the American Ship Building Company yards in Lorain, Ohio, at a cost of $1.3 million, christened by Gertrude Irvin, and on her maiden voyage from June 25, 1938, hauling bulk materials from Two Harbors and Duluth down to U.S. Steel's mills on Lake Michigan and Lake Erie — all of it on the DECC's own history page for the ship. The Irvin was the flagship of U.S. Steel's Great Lakes fleet, 610 feet 9¾ inches overall, and she still holds a Great Lakes record the DECC page says remains unbroken: unloading 13,856 tons of iron ore in two hours and 55 minutes using Hulett unloaders. She entered final layup in 1978, too small beside the fleet's first 1,000-foot ore boat, and is now a museum ship in the Minnesota Slip.
Up London Road stands the mansion. Glensheen was built between 1905 and 1908 for Chester and Clara Congdon, on the University of Minnesota Duluth's own history page: a 39-room Jacobean Revival mansion on a 12-acre estate (its homepage says 12 acres of gardens, bridges and lakefront paths) along the shore of Lake Superior, designed by Clarence H. Johnston Sr. with interiors by William A. French in a mix of Arts and Crafts, Art Nouveau, late Victorian and Federal styles, and photographed for the April 1910 issue of Western Architect. Chester died in 1916 and Clara in 1950, on the Minnesota Historical Society's account; their daughter Elisabeth, the last of the seven children, lived at Glensheen for the rest of her life, never married, and adopted two daughters, Marjorie and Jennifer, in 1932 (the MNHS account dates the second adoption to 1935 in the fuller murder history). Suspicion fell on Marjorie and her husband Roger Caldwell; Caldwell was convicted of the murders in 1978, his conviction was later overturned and he pleaded guilty with a full confession before his release, and Marjorie was acquitted in 1979 — again the MNHS and case accounts, kept together here so no partial version travels alone. Glensheen opened to the public as a museum in 1979, is listed on the National Register of Historic Places, and is today, on its own homepage, Minnesota's most visited historic home, valued at $30 million on its history page, its rooms preserved against those 1910 photographs. Its history page carries a section the mansion itself added: "Remember & Honor — Honoring and remembering those lost in the events of 1977."
The legend
This section is folklore — reported by the tour operator and the accounts cited, and never asserted as fact here.
The restraint starts at Glensheen. Duluth Ghost Tours' own local-haunts page lists the mansion in one line — "Glensheen Mansion – double murder, warning — they no longer talk about hauntings on tours" — and that is the whole of the mansion's ghost record in our material: no named spirit, no reported sighting published by the estate, and an operator who tells her own customers not to expect haunting talk there. Where other mansions in this program market a resident ghost, Glensheen markets preservation, and any apparition story attached to it in wider circulation is not in the collected sources and is not repeated here.
The walk's own repertoire, on the same operator page, is Canal Park's. The William A. Irvin is listed as a regular museum June–September and "The Haunted Ship in October" — a staged seasonal haunt, labelled as such in its own story below, not a claim that the ship is haunted. The Waterfront Plaza / Suites Hotel is listed with Rooms 401 and 302; the Marine Museum "has had some stories"; the Aerial Lift Bridge carries "numerous tragedies" in the operator's summary, and even walking across it is called spooky; both lighthouses carry stories of drownings and suicide in her telling; and Uncle Harvey's Mausoleum, the ruined pier structure in the harbour, is tied to drownings. Around Duluth her list continues — Fitger's, the historic brewery complex; The Depot, the train museum, with "some lingering spirits" in her phrase; and the NorShore Theatre, of which she writes that every theatre has a ghost or two that won't leave when the lights go down. These are one operator's tour traditions, carried as hers: names and room numbers as she publishes them, with no independent documentation in our material, and presented here exactly on that footing.
The DECC's own fall writing leans into atmosphere without asserting hauntings either. Its "Haunted Duluth: Spookier by the Lake" post opens on Lake Superior as "that body of water that doesn't give up her dead" — a line about the lake's shipwreck reputation, in the venue's own words — and rounds up the season: the Haunted Ship, Glensheen's Lantern Tours, Poe from the Minnesota Ballet, and the Depot's Halloween events. Atmosphere, in Duluth's official telling, is a season, not a claim.

Attraction stories
Glensheen
Glensheen publishes no ghost lore, runs no ghost tour, and says so by its choices — and its story here is written to that record, plainly: this is a documented Gilded Age house with a documented 1977 double murder in its past, whose present operator honours the victims and tours the architecture. The mansion's own pages carry the visit. The Classic Mansion Tour is self-guided through the lower level, first and second floors, about one hour; the Full Mansion Tour adds the third floor and attic, about 1.5 hours, both offered daily, at 3300 London Road, Duluth, MN 55804, phone (218) 726-8910 on the site footer. The after-dark offering is the Lantern Tour, Fridays and Saturdays in October: guided only by lantern light, 45 minutes, family-friendly, ending with a souvenir flashlight, framed by the estate as stepping into "illuminated history." The documented house is set out in The history above from the university's own history page and the MNHS account: built 1905–1908 for Chester and Clara Congdon, a 39-room Jacobean Revival mansion on 12 acres, donated to the University of Minnesota Duluth, opened as a museum in 1979, and preserved against Clarence H. Johnston Sr.'s 1910 Western Architect photographs. The 1977 murders of Elisabeth Congdon and Velma Pietila, Roger Caldwell's conviction and later guilty plea, and Marjorie Caldwell's acquittal are likewise set out above with their sources together; the estate's own history page answers them with a "Remember & Honor" section for those lost in 1977, and the local ghost-tour operator warns her readers that the mansion no longer talks about hauntings on tours. No published lore is claimed for Glensheen because, on the collected record, the mansion itself publishes none — and that absence is the accurate story.
