Prot. Schlosskirche

early Gothic church; Particularly worth seeing is the cultivated grave chapel of the Leininger with a splendid Renaissance epitaph

First documented mention in 946; then destroyed several times and completely rebuilt. - The Leiningen burial chapel (added on in 1504) with the final resting place of the Counts of Leiningen is located immediately to the right of the main entrance.
