Castel del Monte is located in the municipality of Andria, which is a rocky hill in southern Italy near the Adriatic Sea. 

The building was completed in 1240, with an octagonal shape of mathematical and astronomical precision that reflects a combination of architectural styles and influences, including that of its founder, Emperor Frederick II.

The Germanic Emperor was a leader of modern humanism and the castle reflects the cultural vision of perfection.
