Tourist Attraction in Enna: Torre di Federico II di Svevia
The Tower of Frederick II represents, together with the Castle of Lombardy, the major architectural symbol of the city of Enna, as well as its most imposing military bulwark of the Middle Ages. The Tower of Frederick II, one of the Federician monuments preserved in the Italian territory, was designed at the court of Frederick II, according to tradition by Riccardo da Lentini and was also used as a summer residence of the Swabian emperor during his stays in Sicily. Its origins date back to the mid-thirteenth century (at the age of Manfredi), which supports the thesis that to want and live there was the Swabian Federico rather than the Aragonese homonym. Another argument in support of the Swabian origin of the monument is the unmistakable geometric layout that also characterizes the other castles of Frederick II of Swabia. The Tower of Federico, at the top of a hillock of the plateau of the city of Enna, at over 950 meters above sea level and a few hundred meters from the geographic center of Sicily, has in the past served as a geodetic reference point for the whole 'Island. Some historical sources say that the ancient astronomers have drawn, starting from the top of the Tower, the Sicilian road system as well as tracing the administrative subdivision in force in the Middle Ages of the three "valleys". The octagonal shape, deriving from the rotation of a square, represents the wind rose. In the Middle Ages, the Torre di Federico constituted, together with the Castle, the defensive system of the then Castrogiovanni. The Castle and the Tower were the "vedette", one of the eastern sector of the city, the other of the western one, then uninhabited. For centuries, a tunnel dug into the rock below the city was active to link them (whose entrance was closed for security reasons). The Tower, 27 m high, has an octagonal shape, and stands on top of a tree-lined hillock chosen at the time of construction for its dominant position a vast landscape. The tower built on the model of the Norman donjon spread on the island has two large rooms inside, one on the ground floor and one on the first floor, with high vaulted ceilings and typical elements of Gothic architecture, like the large umbrella ribs . To connect the two rooms to each other there is a spiral staircase carved into the very thick walls of the tower that reaches the top; here the view sweeps in all directions of the city with a view of the Torre delle Aquile, the Castello di Lombardia, the Duomo and, in the background, up to Mount Etna. The tree-lined space around it is used as a public garden.
