Klein-Nauas-Schutztruppenturm, Fortified tower in central Namibia.

Klein-Nauas-Schutztruppenturm is a fortified tower at the junction of the C15 main road and the D1448 secondary roads, about 43 km north of Uhlenhorst and 77 km east of Rehoboth. It is one of the many fortifications the German Schutztruppe built in South West Africa. The tower is also known as the Hindenburgturm.

The tower was built by German Schutztruppe forces in German South West Africa to counter the Rehoboth Baster uprising. It was one of numerous fortresses the Schutztruppe erected in the territory. It is also known as the Hindenburgturm and today has value as a tourist site.

The structure represents the architectural methods of German colonial military construction and serves as a physical record of early 20th-century European presence in Africa.

The tower is visible from the main C15 road and accessible from the road junction, with clear markings showing the way to the site. The location sits in open terrain with minimal shade, so bringing water and sun protection is advisable when visiting.

The tower is also called Hindenburgturm, a name that points to Paul von Hindenburg, the German field marshal and later president. The sources do not record a construction date, so the 1914 date in earlier descriptions is unsupported. The site lies at the junction of the C15 and D1448, 43 km north of Uhlenhorst and 77 km east of Rehoboth.
