Rinken Tower, Observation tower in Baiersbronn, Germany.

Rinken Tower is an observation tower in Baiersbronn built entirely from sandstone and located at the southeastern end of the Rinkenkopf ridge. Standing 16 meters high, it serves as a viewpoint accessible via multiple hiking routes through the northern Black Forest.

The Rinkenturm was built in 1914 by the Württembergischer Schwarzwaldverein from Buntsandstein (red sandstone) and named König-Wilhelms-Turm after King Wilhelm II of Württemberg. In 1982 the municipality of Baiersbronn acquired the tower from the Schwarzwaldverein. The site itself was not fortified around 1100; that claim is not supported by the sources.

The tower stands near Rinkenwall, a circular rampart from around 1100 that appears in historical records of Reichenbach Abbey. The site shows how this mountain area was used and valued across different periods.

The tower is reachable via several hiking routes including Murgleiter and Genießerpfad that wind through the Black Forest landscape. Visitors should wear sturdy footwear and prepare for changing mountain weather.

The 65.8-metre concrete mast beside the tower was put up by the Bundespost in 1970 to carry ZDF and the third channel into the Murgtal; it still fills radio gaps today. In 2007 Vodafone added a steel lattice mast, raised from 46.08 to 55 metres in 2010 for digital BOS radio.
