Light Square, Adelaide City
The City Mission, one of South Australia’s oldest charity organisations, was remembered through the façade of its 1878 hall in Light Square, Adelaide city, becoming the entrance to a 14-storey building , with affordable and social housing, in 2020.
The mission, with a site chosen in Light Square to confront the area’s “vice and depravity”, would be taken over, a century later, by singles’ discos, next door to a corporate lunch venue with topless waitresses.
The mission's principal 19th Century aim was “evangelisation of the neglected classes” in an area populated by recent Chinese and Syrian immigrants, prostitutes, transients and the very poor needing cheap accommodation. In 1867, evangelical churches in Adelaide city met at James Lyall’s Flinders Street Presbyterian Church to form a city mission, on the model set by David Nasmith in Glasgow in 1826.nWith Richard Berry, formerly of the Scottish Coast Mission, in charge, Adelaide’s City Mission opened at the Rundle Street Ebenezer Chapel, then in Magarey & Co’s former wheat store in Currie Street from 1870, followed by the former Royal Victoria Theatre in Gilles Arcade, off Currie Street, from 1872 until it was sold in 1877.
To enable the City Mission to continue its services, wheat merchant and member of parliament John Darling gave £500 towards a new hall at a “most eligible site” on the west side of Light Square. The locality was one of the city’s red light districts “infested with brothels and soliciting prostitutes as well as having places of music, dancing and revelry”. Such entertainment could be notoriously found in the nearby Shamrock (later Colonel Light) Hotel, also a theatre and concert hall for musical entertainment. life. Many poor working-class families lived in cottages nearby.
Brown and Thompson constructed the hall, apparently to the design of architect H. C Richardson. Opened in 1878, the “plain and neat” building was deliberately functional although it had some high-quality brickwork, including polychrome brickwork to the gable.
Like the Methodist Central missions, the City Mission came to focus more than simply spreading Christianity by looking to the material needs of the underprivileged. This included rescuing girls from “lives of misery” with a cheap-house scheme and working girls' clubs, classes for mothers and free breakfasts to the poor on Sunday mornings, among other services. From 1898, the Mission employed George Gee Wah to work with the Chinese population and Beshara Abotomey with the local Syrian (largely Lebanese) community. From 1883 until 1924, the mission also ran a Chinese school.
The mission continued to be particularly interested in suppressing the “open manifestations of prostitution in the city” and sent a petition to the South Australian government chief secretary requesting changes in the law “to suppress the glaring exhibitions”. During the 1930s great depression, the City Mission distributed blankets and food, and ran a soup kitchen and a women's clinic.
The mission had closed by 1970. It became Regines restaurant, then a nightclub. By the early 1990s, the venue had become Club 69 –its street number– and then Rise with techno music at the turn of the century. Next door in the 1980s, the former Conqueror Tobacco Works e building became Cobbs Restaurant, where topless waitresses served high-ranking courts department executives and other corporate businessmen.
The spirit of the mission returned in 2020 when its façade fronted Spence on Light, 75 apartments providing affordable and social housing, and named for Catherine Helen Spence (1825-1910), suffragist and social reformer, whose statue was on the lawns of Light Square.
