- Unique architectural structure: Castel del Monte stands out for its exceptional precision. With 8 towers emerging from 8 corners, blending Islamic, Gothic, and Romanesque influences, the castle's unique shape fuses elements of both circles and squares.
- Inconclusive purpose: The castle's original purpose remains a mystery, lacking clear indicators of a fortress, such as moats or enclosing walls. Notably, its interior stairs defy the conventional clockwise direction. Some believe that it was a hunting lodge. Perhaps you could be your mystery to solve!
- Polychromatic finish: Colour is a symbol of luxury, and Frederick II indulged in the finest marble for the castle’s interiors. Special limestone and coral breccia give the castle a polychromatic appearance.
- Frederick’s legacy: Emperor Frederick was a learned man in mathematics, philosophy, history and religion. This exceptional project mirrors his diverse passions, fusing cultural and religious elements with scientific precision.
- Most visited monument in Puglia: Castel del Monte draws the maximum number of visitors in the Puglia region. Its popularity skyrocketed when it was later embossed on the Italian 1 cent Euro coin.
- UNESCO World Heritage Site: Owing to its outstanding architectural genius, fairly intact structure and superior conservation efforts, UNESCO has recognised it as a heritage site in 1996.
