The Riedmuseum in Ottersdorf gives an impression of the life and work of the rural population on the Rhine. It consists of a typical farmhouse and farm buildings from the middle of the 18th century. The museum ship "Heini", which is moored in an arm of the Old Rhine near Wintersdorf, is also part of the Riedmuseum. The entire complex is a branch of the Rastatt City Museum and is only open as an open-air museum from March to October.
