The three-nave Gothic church was built by Count Otto II at the end of the 15th century above the outer ward that secured the approach to the castle.
The church was probably consecrated in the year 1501, and has remained largely unchanged since then. It served as a Protestant parish church for centuries and, since 2005, both Protestant and Catholic ceremonies can be celebrated here. Today the Braunfels castle church is a charming and popular place to get married.
