The castle of Lombardy, a symbol of the city of Enna, is an impressive Norman-Swabian fortress that rises to the highest point in the city. with its 26,000 square meters of surface, is one of the largest medieval castles in Italy, together with the castle of Brescia and the castle of Lucera. The castle of Lombardy is named after a garrison of Lombard soldiers in defense of the ancient fortress during the Norman domination of Sicily. From the Pisa tower and the castle we can see that Enna is the Umbilicus Siciliae and probably the Romans nicknamed it for the vastness of the landscapes that embrace vast parts of the island. The castle of Lombardy is the architectural symbol of the city even before the tower of Federico II, its most important non-religious monument and one of the most visited in the Sicilian hinterland. The majestic Cittadella's profile has been equipped with an artistic lighting system that makes it clearly visible from tens of kilometers away. The plant has a triple scenic effect: the illumination of the avenue that surrounds it, the one that projects widespread light on the perimeter walls and the one that rises the Pisan tower. In this way the castle is visible from all four cardinal points.
