Liebenzell Castle is a hill castle above the town of Bad Liebenzell. The fortification was once the most important castle in the Württemberg part of the Black Forest. The castle was built in the 12th century by the counts of Calw. In 1196 the counts of Eberstein were recorded as the castle's owners. From 1220 to 1230 the castle was extended. It was destroyed in the 16th century and in 1692 and rebuilt in 1954.
Today the castle is owned by the International Forum of Liebenzell Castle. It is used as a youth training centre for the Bad Liebenzell International Youth Forum and has a restaurant.
The castle comprises an irregular, pentagonal fortification with a mighty shield wall, into which a square bergfried with a garderobe has been integrated. The great hall (Palas) is decorated with ornamental ogival openings. The six-storey bergfried has a height of 32 metres and has an entrance six metres in height, a wall thickness of two metres and an area of about 9 by 9 metres.
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.
