Sanderburg, Hillside castle in Luxury Hill, Namibia

Sanderburg is the smallest of three castles in Windhoek and sits on a hillside overlooking the city. The building was constructed in the early twentieth century and remains in private ownership with limited public access.

Wilhelm Sander designed and built Sanderburg between 1917 and 1919 as his own residence, and the castle takes his name. It began as a simple dwelling that was altered into a castle-like house only after later construction work. It is the smallest of the three castle-like mansions in Windhoek and remains privately owned today.

The name Sanderburg means "Sander's castle", after the architect Wilhelm Sander, who built it as his own residence. The structure began as a simple dwelling and only became castle-like after later building changes. It is now privately owned, so the medieval-looking features are seen from outside.

The property is located on Kasteel Street and can be easily found using navigation apps. Since it is privately owned, visitors should check beforehand about the possibility of viewing the exterior.

The property includes a large garage on its rear side that stands out from the original design. This addition gives the structure a different character compared to other historic castles in the city.
