Seacliff Lunatic Asylum (often Seacliff Asylum, later Seacliff Mental Hospital) was a psychiatric hospital in Seacliff, New Zealand. When built in the late 19th century, it was the largest building in the country, noted for its scale and extravagant architecture. It became infamous for construction faults resulting in partial collapse, as well as a 1942 fire which destroyed a wooden outbuilding, claiming 37 lives (39 in other sources), because the victims were trapped in a locked ward.
The asylum was less than 20 miles north of Dunedin and close to the county centre of Palmerston, in an isolated coastal spot within a forested reserve. The site is now divided between the Truby King Recreation Reserve, where most of the old buildings have been demolished and most of the area remains dense woodland, and privately owned land where several of the smaller hospital buildings have been renovated.
The need for a new asylum in the Dunedin area was created by the Otago gold rush expansion of the city, and triggered by the inadequacy of the Littlebourne Mental Asylum. In 1875, the Provincial Council decided to build a new structure on "a reserve of fine land at Brinn's Point, north of Port Chalmers". Initial work was begun in the "dense trackless forest" in 1878, though the Director of the Geological Survey criticised the site location, because he felt that the hillside was unstable.
Seacliff Asylum was one of the most important works of Robert Lawson, a New Zealand architect of the 19th century. Known for designing in a range of styles, including the Gothic Revival, he started work on the new asylum in 1874, and was involved with it until the completion of the main block in 1884. At that time, it was New Zealand's largest building, and was to house 500 patients and 50 staff. It had cost £78,000 to construct.
