Breidenborn Castle existed here between the 12th and 15th centuries. Its construction is to be seen in connection with the securing of the Reichsland around Kaiserslautern by the Staufers. In addition to a number of other castles, the "Dieburg" in Alsenborn was probably built during this time. Apart from a few hewn stones, nothing remains of the complex itself above ground; the last remains were removed in the 1950s. On the other hand, boundary stones from this period showing the Breidenborn coat of arms have been preserved in the vicinity.
Daniel Häberle and his niece Katharina, both from the Daubenbornerhof, devoted themselves to researching the castle and drew up a site plan of the area. As a result, this was a moated castle surrounded by dammed waves and could only be reached via a drawbridge. To the west of the castle there was a separate tower and a service yard outside the actual castle area. With such early structures, it is not uncommon for them to have been built from ruins from Roman times. That could also apply here, because during excavation work in the middle of the 20th century. Roman pottery was found. A note has also been handed down from the residents of the Daubenbornerhof: When the researcher Hermann Hahn from Berlin was looking for the remains of the castle in 1896, the residents of the court showed him the spot and reported that a Roman castle once stood there. The older field names Breitenwäldtlin and Bottelhalten. Might actually contain remnants of Celtic-Roman terms for a "border".
