The Alte Feste is a fortress and museum in downtown Windhoek, the capital of Namibia.
The building was designed by captain Curt von François to serve as headquarters of the imperial German Schutztruppe during German colonization of South West Africa. The location of Windhoek, which was deserted and completely destroyed at that time, was chosen because the Germans felt it would serve as a buffer zone between the Nama and Herero tribes. The fort was, however, never involved in any military action.
The foundation was laid on 18 October 1890 by then Schutztruppe private Gustav Tünschel. The building was redesigned multiple times during the first years; its final layout was only completed in 1915. It consists of an inner courtyard with high walls and accommodation for the troops on the inside, as well as four towers.
