The Roman theatre in Vienne was built around 40-50 AD and is considered to be one of the largest theatres in Roman Antiquity with a capacity of 11500 seats and a diameter of 130 metres. In the 2nd century it was double sized by a second smaller theater, the odeon, which was built nearby on the southern slope of the ravine of Saint-Marcel.
The annual Vienne Jazz Festival has been held on the ancient theatre since 1980.
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
