The first Silkeborg Castle, a primitive wooden building surrounded by palisades, was built in 1385. It was later replaced by a stone building, and again in the early 16th century by a main building in stone, a courtyard and a stable yard. Silkeborg Castle received royal visits on several occasions. Both Frederik II and Christian IV were regular overnight guests in the main building “Det Store Stenhus” (the great stone house), during hunting trips and the like in Central Jutland. The castle was badly damaged during the Swedish wars in the 17th century, when Silkeborg was occupied by Swedish troops, who ravaged the castle buildings, no fewer than three times. Having been in a state of disrepair for years, the last remains of the castle were demolished in 1726. Today, the layout of both the main building and the courtyard is marked by embankments. There is access to the area via a bridge across the River Gudenå at Lake Silkeborg Langsø and from the Papirfabrikken area.
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.
