Royal Hibernian Military School
The Royal Hibernian Military School was founded in 1769 as the Hibernian Asylum, by the Hibernian Society, a philanthropic organisation founded in Ireland in 1769 after the Seven Years' War. The Society petitioned the King for a charter on 18 April 1769 and the Hibernian Society was incorporated under Royal Charter on 15 July 1769. The first meeting of the Governors was held on 6 November 1769 in Dublin Castle.

In 1922 the school and boys moved to Shorncliffe and the buildings were handed over to the newly independent Irish Government.

Medical use
The buildings were used as a hospital by the Irish Army. In 1948 it was transferred to the Dublin Health Authority and turned into a Chest Hospital. In 1964 it became a facility for older patients and provides today accommodation for dependent older people. St Mary’s Hospital undertook a major renovation in late 2020 bringing facilities to that of a modern healthcare facility. St Mary’s Hospital has increased its inpatient capacity from 48 to 101 sub-acute rehabilitation beds providing support to acute hospitals in the region. Phase 2 of the infrastructure upgrade is to include the expansion and modernisation of the hospital's x-Ray department. The Phoenix Park Community Nursing Unit (PPCNU) has 150 beds and provides residential care to older adults.
