Symbol of a harmonious blend of cultural elements from Northern Europe, the Muslim world and classical antiquity, Castel del Monte, a unique masterpiece of medieval architecture, has been on the UNESCO World Heritage List since 1996. Built directly on a rocky bank, the Castle is known for its octagonal shape.Eight towers in local limestone are grafted onto each of the corners.The courtyard, also octagonal in shape, is characterised, like the entire building, by the chromatic contrast obtained thanks to the use of coral breccia, limestone and marble.
