Hinterburg is one of the four castles in a string along the Neckar River, built by the von Steinach family in the 1100s. It is the oldest of the four, serving a strategic purpose in allowing the lords to observe the Neckar and Steinachtal. One of the earliest records mentions Bligger von Steinach, c. 1160. His son, Bligger II, who was also a famous minstrel of the time, added much of the outer wall that helped drastically improve the castle's defensive posture. At one time it also had a dry moat with a drawbridge. The castle continued to be used up until the 1600s, largely in the service of the Elector Palatine. Afterwards it began to decay from neglect as it lost its importance in the era of cannon. There is no indication that it was ever seriously besieged.References:
Castel del Monte, located in the municipality of Andria, rises on a rocky hill dominating the surrounding countryside of the Murgia region. A unique piece of medieval architecture, it was completed in 1240. The castle’s location, its perfect octagonal shape, as well as the mathematical and astronomical precision of its layout all reflect the broad education and cultural vision of its founder, Emperor Frederick II.
As a leader of modern humanism, the Germanic Emperor brought scholars together in his court from throughout the Mediterranean, combining Eastern and Western traditions. The castle’s unique design, an octagonal plan with octagonal towers at each angle, represents a search for perfection. Interior features reflect Eastern influences, such as the innovative hydraulic installation used by Frederick II for bathing in accord to the typical Arabic customs.
The site is of outstanding universal value in its formal perfection and its harmonious blending of cultural elements from northern Europe, the Muslim world and classical antiquity. Castel del Monte is a unique masterpiece of medieval architecture, reflecting the humanist ideas of its founder, Frederick II of Hohenstaufen.
