Hässelby Castle (Hässelby slott) was built first in the 1640s by the riksråd Karl Bonde, who owned it until his death 1652. The original architect was Simon de la Vallée and the castle was finished about the 1660s by his son Jean de la Vallée, when Karl's son Gustaf Bonde owned it. The Bonde noble family owned the castle until 1931, when Stockholms stad bought it until 2010. Since 2010 SIVAB own the castle. Today Hässelby is opened for weddings, parties and conferences.
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.
