Looking every inch the fairy-tale castle with its setting atop a rocky outcrop and sturdy towers, medieval Burg Mauterndorf is the village's pride and joy. It was built in the 13th century by the archbishops of Salzburg on the site of a Roman fort. The castle now houses a regional museum and provides the backdrop for various cultural events.

It is believed that in the Middle Ages the main road passed directly through the castle courtyard and tolls were extracted from road users.
