About Castel del Monte
The name Castel del Monte means Castle of the Mountain in Italian. The building is a citadel and castle from the 13th century. It sits on a hill in Andria, in southeast Italy's Apulia region, at an altitude of 540 meters (1,770 ft). King Frederick II had it built in the 1240s on lands that came to him from his mother, Constance of Sicily. It has no moat or drawbridge, and some have doubted that it was meant as a defensive fortress, but archaeological work suggests a curtain wall once surrounded it.
Its bold octagonal plan is what the castle is best known for. The main block is an eight-sided prism, with an eight-sided tower standing at each corner, and both floors have eight rooms around an eight-sided courtyard. Its walls rise 25 m (82 ft), and each of the eight corner towers is 26 m (85 ft) high. Across, the castle measures 56 m (184 ft). The ornate main entrance faces east and has a pediment on thin fluted pilasters, classical elements that may reflect Frederick II's interest in Greek and Roman architecture.
A document from 1240 has Frederick II telling the governor of Capitanata to complete certain works at the castle, which was never finished. Later it served as a prison and as a refuge during a plague. In the 18th century, the marble and other furnishings inside were taken away. The Italian State bought it in 1876 for 25,000 lire and began restoration in 1928. UNESCO named it a World Heritage Site in 1996.
