St Peter's Cathedral, Armidale, Anglican cathedral in Armidale, Australia.

St Peter's Cathedral is an Anglican cathedral at 122 Rusden Street, Armidale, between the town hall and Central Park. Built from 1871 to 1938, it was designed by John Horbury Hunt and Bishop James Francis Turner using local "Armidale Blue" brick from Saumarez, New England granite from Uralla and district timber. Its small-scale Gothic design layers patterned brickwork, flying buttresses, arching, toothing and moulded brick.

Construction began in 1871 under architect John Horbury Hunt, replacing a timber church that stood from 1850. Its completion represented a significant shift in the religious infrastructure of the growing settlement.

The cathedral is the mother church of the Anglican Diocese of Armidale and the seat of its bishop, a role held by James Francis Turner for 23 years from 1869. Turner, who had trained four years in an English architecture office before turning to theology, designed much of the fit-out and furnishings himself; they were built to his specifications in England and shipped out.

The cathedral sits prominently at a street corner and can be viewed from outside to appreciate its architectural details and facade. The grounds and surrounding area are accessible for a quiet walk and to observe the building from different angles.

The cathedral's brickwork is not plain: Hunt layered patterned courses, toothing and moulded brick with a flying buttress, using locally sourced "Armidale Blue" brick from Saumarez, granite from Uralla and district timber. The small-scale design deliberately complicates rather than simplifies its Gothic detailing.
