The Emperor's Palace in Milan was founded in about 291 AD by emperor Diocletian. Here Constantine and Licinius issued the Edict of Milan in 313 AD.
Residential and ambassadorial sectors, private baths and the circus, where the Emperor appeared solemnly to his subjects, and victory in chariot races became symbolic of Imperial victories, took up an entire sector of the city. The only visible traces of this vast polyfunctional quarter, which stayed in use perhaps up until the tenth century, are the remains of an ambassadorial building which had central heating; many archaeological remains are probably to be found under the buildings around Via Brisa.
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.
