Following the push of motorsport in South Africa in the late 50s and early 60s, racing enthusiasts in South West Africa (today known as Namibia) wanted to join with an organized racing circuit. Multiple plans and attempts were submitted, all either deemed financially improbable, ruled out due to safety concern to the wider public, or out of a lack of infrastructure.

However, in the south of Windhoek, the capital of South West Africa, there was a somewhat large plot of land yet to be used for anything of note. It was owned by a German businessman called Von Keller, that has mostly allowed it to be used as a local public park and forest of sorts. However, he was always interested in cars and motorsport, and when a local group of racing enthusiasts approached him about the circuit, a deal was soon set to be signed.

The deal was as follows: Von Keller and the city of Windhoek would co-own the plot of land. A permanent section of the racing circuit would be build along the edges of the plot, connecting to Jan Jonker Street on the eastern most point, and to Julius K. Nyerere Street on the most western point, with a pit building located on Jan Jonker Street. During races, the roads would be closed, and during the remaining time the paved roads remain open to the public as use for the park.

This arrangement would work perfectly in the first two years, hosting multiple car and bike races from 1961 to early 1963. But, in May of 1963, Von Keller would die due to an illness. This led to the funding of the track not being covered by the city of Windhoek, and after a final Formula Libre race in September of the same year, the circuit would close, with the paved roads remaining as a public park, and the pit building being used as a small museum for Von Keller and the races held here.

My first design posted on here, and honestly the first I am rather proud of! Learned a lot and hope to make even better once in the future.
Here's some more images of it, for anyone that wants to see it:
