Burg Metternich was mentioned in documents first time 1268, when it was owned by Johann von Braunshorn. It is thought the castle is even older, with some historians indicating 1129 as the year of construction. Until the first half of 17th century, the castle was owned by Counts von Nassau-Dillenburg.
The castle was not damaged badly before 1689, when French army destroyed the castle during the Nine Years' War. It was never completely rebuilt.
The last member of the family to own the castle was Klemens von Metternich, one of the most famous diplomats of the Austrian Empire – he was foreign minister from 1809 to 1848.
Today there is a hotel and restaurant.
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.
