Queen Victoria Sanitorium opened on 18 February 1903 at Wentworth Falls in the Blue Mountains as a tuberculosis sanatorium for men. The original house was built for Sydney businessman Kelso King, who sold the property to the Queen Victoria Diamond Jubilee Homes for Consumptives Fund after the death of his wife Irene in 1900. The full complex was designed and built between 1902 and 1921. The sanatorium ran for 55 years before becoming a hospital for the aged and chronically ill in 1958 and finally a nursing home, which closed in May 1999. The site is on the local heritage register (item Wf025) but is not on the NSW State Heritage Register. Most of the complex is now in ruin.
