Wurzelbrink, Mountain summit in Wiehengebirge, Germany

Wurzelbrink is a 318.6 m high hill in the Wiehen Hills, 2.2 km south of Lübbecke's town centre. On its summit stands the Lübbecker Wartturm, a small watchtower built in 1857 that now serves as an observation tower. Tall trees around the tower block much of the view, leaving mainly a restricted outlook south over the Ravensberg Hollow toward the Teutoburg Forest and Bielefeld's TV tower.

The Lübbecker Wartturm on the summit was built in 1857. It is the highest publicly accessible point in the Wiehen Hills. Trees now partly block the views it once offered; raising the tower by a few metres, as was done at the Nonnenstein, would restore clear views.

The spring on the western slope has no official name; locals have long called it the Mickey Mouse Spring as a joke. They fill cans and containers here for household use, and an unofficial analysis found low pollutant levels but a relatively high copper content.

Several marked hiking trails lead to the summit and connect with other paths in the area for longer walks. Access is possible from different starting points and well signposted.

A natural spring on the western slope flows from groundwater with higher copper content but remains clean and drinkable. Some hikers still use this water that emerges from the ground today.
