Friedrich was appointed reeve of Beuron Archabbey. A tunnel may have connected the castle to this crypt. Legend has it that Friedrich built this abbey to resolve a problem he had with Emperor Friedrich II, after he had refused to contribute troops when the Emperor was raising an army.
Friedrich has a long-running conflict with the Counts of Hohenberg, which was settled when King Rudolf I of Germany mediated in 1286. Friedrich was described as pious and respectful. During his reign, the county of Zollern reached the peak of its influence.
They added a crypt where members of the Zollern family would be buried.
