The Castello Normanno ('Norman Castle') in Paternò was built in 1072 by Count Roger I of Sicily to protect the Simeto valley from Islamic raids. The first nucleus of the fortress was soon enlarged, and it subsequently lost its original military functions. Under Henry VI it was made the seat of the Count of Paternò, assigned to his fellow Swabian Bartholomew of Luci. Later the castle housed kings and queens, such as Henry's son Emperor Frederick II, Eleanor of Anjou and Blanche I of Navarre, as the castle had been included in the so-called Camera Reginale estates ('Queen's Chamber') by King Frederick III of Sicily.
The Chamber was abolished in the 15th century, and in 1431 the castle was acquired by the Special family; until 1456 it was owned by the Moncada family. Used as a jail, in the following centuries it became increasingly decayed, until restoration work begun in the 19th century brought it back to its ancient prominence.
The castle has a rectangular plan, on three floors, with a height of 34 m. Originally, it had Ghibelline-style merlons, of which today only remains can be seen. Notable is the colour effect created by the dark shade of the stones and the frames of the Gothic-style mullioned windows, in white limestone.
The first-storey houses several service chambers and the Chapel of St. John, decorated with precious 13th-century frescoes. The piano nobile houses a large Weapons Hall. The king's residence was located in the upper floor.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
