In 1100, a nobleman named Heinrich named himself after the old Clingenburg (castle). He belonged to the noble family of Reginbodo. The Clingengurg castle was built around 1160-1170 by Conradus Colbo, who was cup-bearer to Emperor Friedrich Barbarossa.
About 1250, the Bickenbach noble family moved into the castle; the Bickenbachs later held many influential offices in the Holy Roman Empire and many a time turned up in Imperial politics as brokers.
After the Bickenbachs died out in 1500, the town, castle and lordly domain passed to the Archbishop of Mainz. Clingenburg castle was destroyed by the French in the late 17th century and never rebuilt. It remained a ruin.
In the 20th century Clingenburg was opened up to tourism with a restaurant and a lookout platform affording visitors a view over the old town and the Main valley. Since 1994, the Clingenburg-Festspiele have been taking place, drawing many visitors each year with changing plays and musicals.
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.
