Wilhelms-Tower, Observation tower in Wölpinghausen, Germany.

Wilhelms-Tower is a sandstone observation tower standing 25 meters high on the Wölpinghauser Berg. From the top, visitors look out toward Porta Westfalica and the rolling countryside around it.

Prince Georg zu Schaumburg-Lippe ordered the tower's construction between 1846 and 1848 as both a surveying tool and a work project. It replaced an earlier house called Bergleben that once stood on the same spot.

The tower is looked after by the Kulturerhaltungsverein Bad Rehburg e. V. and opens on Sundays and public holidays. Around it are a barbecue area with a hut and the rebuilt "Haus Bergleben", now a restaurant for hikers. The name recalls Count Wilhelm zu Schaumburg-Lippe, who lived in the original house on this spot until his death on 10 September 1777.

Climbing to the observation platform requires ascending 106 steps, so sturdy footwear is helpful. Plan your visit when the weather is clear, as the views from the top depend on visibility across the landscape.

The tower takes its name from Count Wilhelm zu Schaumburg-Lippe, whose former residence once occupied this hilltop. This link to the local noble family remains visible in the structure's name today.
