Turnhalle

The Turnhalle is a building in Windhoek, the capital of Namibia. Built during the era of Imperial Germany's colonisation of South West Africa, it has been through a variety of uses, most prominently as the venue for the 1975–1977 Turnhalle Constitutional Conference, an attempt to quell armed resistance waged by the People's Liberation Army of Namibia against South African occupation. The Turnhalle housed the Tribunal court of the Southern African Development Community until disbandment in 2012.
