The Montalbano Elicona Castle is considered as one of the most beautiful monuments in Sicily. It was built in the 12th century by the Holy Roman Emperor, Frederick II on pre-existing byzantine and Arab walls. The intent of Frederick II was to provide Sicily a series of strong defensive buildings around the island. The well preserved extensive walls of the castle are easily seen throughout the town. From on top of the Valley the King could control the whole area and the nearby Nebrodi Mountains.
The small medieval winding roads lead up to this charming castle that was home to many kings and nobles like Luis King of Sicily and Frederick the Simple. The ongoing restoration work in progress closes up some areas of this site but it is still well worth a visit. Interesting are the rooms with armours on display and the small museum with musical instruments. The Royal Chapel of the Byzantine era is truly impressive! Apparently Arnaldo da Villanova was buried here, a famous character connected to this castle who died in 1313 in genoa and was a doctor, alchemist and a religious writer of great influence in the european courts.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
