its harbourside location, the topography, natural and introduced vegetation, open space and a variety of buildings and structures. It has historic associations with early settlement, the advent of the Marist order in Australia and with mental health care for more than a century. The main building and site was the first permanent home of the Marist Fathers in Australia, their base for the South Pacific, and their first, purpose-built Procure house. It is integral to the history of the original Gladesville Asylum (later renamed) for over 100 years, and hence the history of psychiatric care in NSW. The main building (1847–1874, a Colonial Regency building) is a major landscape element, being a fine example of the colonial regency style of architecture, designed by William Weaver. In addition the site contains outbuildings, remnant structures and archaeological features that are heritage items in their own right, areas of natural vegetation and historic plantings, as well as evidence of the use of the building for farming purposes. The significance, meaning and interpretation of the building, outbuildings, archaeological sites and landscape are integral to one another.

The Priory was the first permanent home of the Marist Fathers in Australia, providing a base to their operations in the South Pacific and their first, purpose-built Procure house. The Marist Fathers have retained a nearby base in Hunters Hill to the present day. For well over 100 years the Priory has been integral to the history of the original Gladesville Asylum, later Gladesville Psychiatric Hospital – itself a significant site in the history and development of mental health care in New South Wales. The site provides rare evidence of its continued agricultural use, unusual in an area that is otherwise built up. The land was farmed first by Thomas Stubbs from the 1830s, and then by the Marist Order who extended vineyards and food production for their own consumption. For more than 60 years the area was farmed by patients for the
