The exact history of the Wolfenstein Castle is unclear. The archaeological excavations have dated the construction to the mid-12th century. The first written document dates from 1283 when Gottfried von Sulzbürg changed his name Wolfenstein and started the nobility. Hans von Wolfenstein died childless in 1462 and the castle was moved to the possession of Bohemian (Czech) king. Wolfstein lost its importance in the 16th century after been damaged in War of the Succession of Landshut in 1504. The castle was abandoned and fell into disrepair.
Today, the ruins of Wolfenstein are in good condition. It went through extensive excavations and renovations in the 1990s.
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.
