Burg Clam is a medieval hilltop fortress located in the Mühlviertel region of Upper Austria, continuously inhabited by the Clam-Martinic family since 1454. The castle complex features a preserved residential wing, a vaulted armory, and an inner courtyard that hosts high-capacity outdoor music events. Its architecture spans centuries, incorporating Romanesque foundations and Renaissance extensions. The onsite museum displays collections of historical weaponry, period furniture, and ancestral family portraits. The site remains a private estate, with select portions opened to the public for guided tours.
