Unesco world Heritage site since 1996, the castle was built by Emperor Frederick the 2nd in 1240 as a hunting residence and was considered a stupor mundi of the times. Its spectacular position on top of one of the highest hills of the Western Murgia gives an idea of the grandeur of the Emperor who commissioned it. The spectacular building has an octagonal floor plan with a tower at each corner. Inside there are sixteen halls decorated with elements in classical, gothic and Arab styles. The stunning mosaic decorations are still visible on the floor. The castle is the most visited monument in the Apulia region due to it’s extremely characteristic architectural and decorative elements and breathtaking position and is used for numerous exhibits, conferences, concerts and cultural events.
