Ou Raadsaal, Parliament building at Church Square, Pretoria, South Africa

The Ou Raadsaal is a parliament building at Church Square in Pretoria with Renaissance Revival architecture. Its facade features grand columns, decorative details, and three levels of carefully worked stonework and windows.

The South African Republic commissioned the Ou Raadsaal as its new seat of government; construction began in February 1889, and President Paul Kruger laid the cornerstone on 6 May 1889. Dutch architect Sytze Wierda designed it, and Orkney-born builder John Johnstone Kirkness completed the work in December 1891 for £82,500. The Volksraad met here from May 1890, and the building served as parliament until the republic's annexation in 1902 abolished that body.

The tower statue is said to depict Athena, Greek goddess of wisdom, industry and agriculture. Above the entrance, a replica of the South African Republic's coat of arms replaced the British one during the 1962 restoration, with the Dutch motto "EENDRAGT MAAKT MAGT" (unity makes strength) beneath it. Inside, the Volksraad hall was returned to its original state, its walnut chairs upholstered in green Moroccan leather and set in their original horseshoe arrangement after the British occupation had pushed them against the walls.

The Ou Raadsaal stands on the south side of Church Square, in Pretoria's city centre, and is used today by the City of Tshwane Metropolitan Municipality. It is a working municipal building rather than a museum, so visitors should check access before planning a look inside; the exterior and the square can be seen at any time.

The tower statue represents Athena, Greek goddess of wisdom, industry and agriculture. During the 1962 restoration, the British coat of arms above the entrance was replaced with a replica of the South African Republic's coat of arms, beneath which the Dutch motto "EENDRAGT MAAKT MAGT" (unity makes strength) is carved.
