All Hallows' School Buildings, Catholic school in Fortitude Valley, Australia.

All Hallows' School Buildings sit at 547 Ann Street in Brisbane and consist of several structures housing classrooms, a convent, and administrative offices arranged on a landscaped site. The complex serves a secondary school for female students spanning from year five through twelve in the heart of the city.

Bishop James Quinn bought Adderton, the former home of Dr George Fullerton, for £6,000 in December 1863, and the Sisters of Mercy moved in on 1 November 1863 with boarders from St Stephen's school. The convent and school were thus established in 1863 on Petrie Bight, the order's first permanent Queensland site. Adderton itself, a two-storey stone house with basement, is thought to have been built in the late 1850s by builder Andrew Petrie after Fullerton bought the land in 1858.

The school's name is thought to come from Mother Vincent Whitty's All Hallows' College in Dublin, itself recalling the seventh-century All Hallows'-by-the-Tower in London. The Sisters of Mercy, a teaching order founded in Ireland by Catherine McAuley in 1831, ran All Hallows' as a "select" school whose fees helped finance parish or "poor" schools such as St Stephen's.

The school is centrally located in Brisbane and relatively easy to find, though public access to the grounds is restricted during school hours. It helps to check ahead about visiting conditions so you can see the buildings respectfully from outside or arrange a proper visit.

Adderton was built for Dr George Fullerton, who sat on Queensland's first Legislative Council; Bishop Quinn bought it for the Sisters of Mercy in December 1863 for £6000. Builder Andrew Petrie designed the two-storey stone house with basement, and its geometric stair, entrance door with elliptical fanlight, shuttered windows and fireplaces survive inside the enlarged convent.
