Ferdinand was one of the most important collectors in history. The armoury shows masterpieces of European plating. The Kunst- und Wunderkammer is the only Renaissance chamber of art preserved in its origi-nal location and is thus an incomparable cultural monument.
The Spanish Hall is one of the most beautiful Renaissance halls. Frescoes in grisaille painting adorn the inner courtyard of the Upper Castle. The Bathing Chambers of Philippine Welser are a cultural historical rarity. The Castle Chapel is dedicated to St. Nicholas. In the Strasser glass collection you can see precious Renais-sance and Baroque glasses. During summer months, the three floors of the Habsburg Portrait Gallery are accessible as well. The paintings there are by famous painters such as Hans Burgkmair, Lukas Cranach the Elder, Giuseppe Arcimboldo, Peter Paul Rubens, Diego Velázquez, and others.
