Baltadvaris Castle was a fortified manor house, earlier sometimes classed as a bastion castle. The masonry castle with wooden fortifications was constructed by Swedish in the 16th century, in a bend of the River Siesartis, in order to secure the road from Vilnius to Riga against attacks from Livonia. It used to be the property of the princely Giedraičiai (Giedroyć) family. The neglected castle and fortifications gradually fell into ruins. Today only the foundations remain as well as parts of the walls and of the castle gates, together with several cellars.
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.
