There are only a few remnants of the Beilstein castle ruins, but it was nice to admire this highlight,
The natural and cultural monument castle ruins Beilstein is one of the smaller imperial ministerial castles. The Felsenburg is located about two kilometers east of Kaiserslautern on the B37 (to Hochspeyer), 313 m above sea level. NN. The ruin probably owes its name to the ax shape of the castle rock.
Probably in the 12th century, Duke Frederick II of Swabia ("Duke Frederick the One-Eyed") had the castle built. In 1185 it was mentioned that the castle was owned by Ministerial Merbodo von Beilstein.
In 1212, Merbodo von Beilstein sealed together with his brother Wernher von Wartenberg as witnesses in the Wilenstein renunciation, in 1234 King Henry VII allowed the Bylenstein castrum to be rebuilt.
Between 1420 and 1455 the castle was violently destroyed. No reconstruction followed. The ruins passed into the hands of Flörsheim and the Electoral Palatinate. In 1464, the last time a Beilsteiner was mentioned was the Hochstiftisch-Speyer chef Hans von Bilenstein. After the Flörsheim family died out in 1665, the castle was completely owned by the Electoral Palatinate.
Around 1900, the Palatinate Beautification Association cleared part of the site and carried out security measures. As a result, however, archaeological find zones were partially destroyed. At the end of the 1950s, excavations proved that a facility must have existed before it was first mentioned, the dimensions of which were obviously much larger than the part of the facility that has survived today, which essentially consists of the masonry of the keep.
Beilstein Castle has been owned by the city of Kaiserslautern since around 1990.
