Built by the knights of Leyben around 1113, the castle had an eventful history and constantly changed hands. The 800-year-old castle towers high above the surrounding countryside on its mighty cliff. One of its highlight features is a unique 17th c wooden coffered ceiling, which depicts the Cycle of Planet Deities by Hendrik Goltzim from 1569. Leiben was not able to acquire this significant architectural landmark until 1989. At that time the municipality carefully restored the castle as a listed historical building and made it available to locals and visitors. The castle vaults contain an agricultural equipment museum with exhibit items from the first-ever generation of tractors and impressive moving trial models that were individually made. Open on Sundays and holidays from 10 a.m. to 5 p.m. from Easter Monday to the end of October. Group tours are available at any time for parties of 10 or more upon prior arrangement.
