Just before Grein, the Danube Cycle Path offers a stunning view of Greinburg Castle, which sits majestically overlooking the Danube. Begun around 1488, this castle is considered the oldest inhabited castle in Austria and is one of the country's most important Renaissance buildings. Built by the Counts of Losenstein, it impresses visitors with its elegant arcaded courtyard and famous diamond-vaulted ceiling. Since the 17th century, the castle has been owned by the ducal family of Saxe-Coburg and Gotha. Today, it houses the Upper Austrian Shipping Museum and is a popular destination for day trips. A short stop on the Danube Cycle Path is well worth it – offering a magnificent view of both history and the Danube.
