Festung Rüsselsheim, also known as the Rüsselsheim Fortress, is a historic fortification located on the banks of the Main River. Originally constructed in the 14th century by the Counts of Katzenelnbogen, it served as a strategic defensive stronghold and residential palace. The complex is now home to the Museum Rüsselsheim, which documents the transition of the region from an agrarian society to an industrial center. Visitors can explore the remnants of the defensive walls, the moat, and the well-preserved structural masonry of the main keep. The site functions as a regional cultural hub, hosting temporary exhibitions and local historical displays. It stands as a rare example of a moated castle preserved within an urbanized industrial landscape.
