Today, only 1 free-standing tower remains of the former Schwabsburg. This consists of massive ashlars and was once the keep of the castle. Located on a Roman military road leading to Mommenheim, it once served to protect and maintain the power of the Staufers in and around Nierstein and Oppenheim. It is unknown who built the castle, but a connection to the construction of Landskron Castle in Oppenheim is assumed, which suggests that it was built between 1125 and 1245. The destruction of these buildings took place in 1620 during the 30 year war at the hands of the Spaniards. There are no other remains of the complex, but old sources report about a dining hall, a ring wall and various residential and farm buildings. Translated with www.DeepL.com/Translator (free version)
