The House of Thun und Hohenstein, also known as Thun-Hohenstein, belonged to the historical Austrian and Bohemian nobility. There is one princely and several comital branches of the family. The princely branch of the family lived at Děčín (German: Tetschen) in Bohemia for more than 200 years. The family maintained an expansive library, including two important albums depicting artistically and technologically innovative armour made for the Habsburg court during the fifteenth and sixteenth centuries.[1]
