Larnach Castle, perched atop the Otago Peninsula above Dunedin on New Zealand's South Island, is the only castle in New Zealand and the home of one of the country's most layered and melancholy ghost stories. Built between 1871 and 1887 by wealthy merchant and politician William Larnach for his first wife Eliza Guise, the 43-room Gothic Revival mansion became the site of a cascade of family tragedies: Eliza died at 38 of apoplexy in 1880; Larnach's second wife Mary (Eliza's half-sister) died suddenly in 1887; Larnach's beloved daughter Kate died of typhoid at 26 in 1891; and Larnach himself — after discovering that his third wife Constance de Bathe Brandon had been having an affair with his son — committed suicide in a committee-room of the New Zealand Parliament on October 12, 1898.
The castle's most-reported apparition is that of Eliza Guise, described as a slim woman in a long white Victorian dress who has been seen at the top of the ballroom staircase, in Kate's former bedroom, and in the ballroom itself. Employees, visitors, and the Barker family (current owners since 1967) have reported hundreds of individual encounters catalogued in the castle's guest log. Other reported figures include a 'sad man' in a dressing gown in the Smoking Room (identified with Larnach himself) and a young woman weeping in the small bedroom assigned to Kate. The castle's ballroom — an extraordinarily ornate space added for Kate's 21st-birthday party that she never lived to celebrate in — registers persistent cold spots and unexplained sounds of piano music and laughter.
The Larnach family's chain of tragedies, the castle's isolation on the windswept Otago Peninsula, and the continuous stewardship of the Barker family (who have insisted the property remain a lived-in home rather than a museum) have combined to keep Larnach's ghost tradition vivid and first-person rather than commercial. The castle has been investigated by Ghost Hunters International and the New Zealand Paranormal Association, both of which have produced evidence consistent with long-term resident activity.
