The Alte Brücke (Old Bridge) was erected by Charles V in 1546 and is one of the oldest constructions in Saarbrücken. The Alte Brücke connects Alt-Saarbrücken and St. Johann. Originally it consisted of 14 arches, but now only 8 remain. It was destroyed during WWII and subsequently rebuilt before being shortened in the early 1960s to make room for the urban expressway which passes through central Saarbrücken running parallel to the river.
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.
