The Priory, Gladesville, Heritage-listed former farm, convent and mental health facility in Gladesville, Sydney, Australia

The Priory is a former farm, convent and homestead on Manning Road in Gladesville, built from 1847 to 1874. Its main building, designed by William Weaver and Henry Hardie Kemp, is a Palladian or Old Colonial Regency structure with a long eastern stone-flagged verandah and a courtyard formed by side wings. The plan incorporates Thomas Stubbs's pre-1847 sandstone cottage as a northern wing.

Thomas Stubbs bought two allotments at the head of Tarban Creek in 1835 and built a sandstone farmhouse. In 1847 he sold the land to Fr. Jean-Louis Rocher of the Marist Fathers, who in 1857 built Villa Maria, designed by William Weaver, as a base for Pacific missions. The site later served as Gladesville Hospital and Asylum.

The Marist Fathers bought the farm in 1847 as a base for their South Pacific missions, storing goods here for the island stations and using the house for missionaries' rest and recuperation. A wooden chapel on the site held the body of St Peter Chanel, Proto-martyr of Oceania, from 7 May 1849 until it was taken to France before February 1850.

The Priory stands on Manning Road in Gladesville, within the Municipality of Hunter's Hill, on land above the head of Tarban Creek. The building is a vacant former homestead and is proposed for community arts uses, so it is not open as a regular attraction; confirm access arrangements before travelling.

The wooden chapel once held the remains of Saint Peter Chanel before they were moved to France. This connection links the place to an important moment in Pacific missionary history.
