Leiningen Castle, located in the town center, has a multifaceted past. The shell of the building was completed in 1708, but no further extensions were made at first as the owner at the time, Count Carl Ludwig von Leiningen-Dagsburg-Falkenburg, died in 1709. His wife, Countess Anna Sabina von Nostitz, sold the estate to the Electoral Palatinate Privy Council in 1717 due to financial hardship. In the years that followed, the castle fell more and more into oblivion until 70 years later, in 1787, a member of the Leiningen family once again became the owner. Count Wilhelm Carl zu Leiningen-Guntersblum renovated the impressive building and extended it further for the purposes of the count's family. In 1833, the castle became the property of the municipality of Guntersblum and has been officially used as the town hall since 1834. Since 2014, the building has also housed an administrative office of the Rhein-Selz municipality. The basement is also used as an event space. The area in front of the castle was originally laid out as a sprawling castle park. Over the course of time, this park was pushed back by various buildings, and today a single fountain holds its position as a relic of days gone by.
