Audunborg or Hegrenes-borga castle was built in stone from 1276 to 1286 probably by English craftsmen from Bergen. The rectangular building was 22 by 13 metres and had three stories. There was a store room in the ground floor, living quarters on the next floor, and a feast hall in the top floor. It had large windows and arches. The building itself had water on three sides and was thus easy to defend. It is also thought that a moat or castle wall was part of the fortifications. Recent research claims that Audun himself spent little time in his castle as his activities kept him either in Bergen, in the east of the country or abroad. As a baron, Audun Hugleiksson was allowed to keep a hird (armed retinue) a right otherwise reserved for the king. This hird would defend him on his travels and when he was at home in Audunborg.
In Norway, only the King and the Church had the funds to build in stone and Audunborg along with Isegran by Glomma, built by Alv Erlingsson, are the only two known examples of private stone castles in Norway. Stories about Audun remain in local folklore and one story includes him burying all his money and sinking a silver table into the lake Jølstravatn before departing for his last trip to Bergen.
Today, only the ruins remain of the castle that stood at the tip of Hegreneset by Jølstravatn in Sunnfjord. It was first excavated in 1934 and is probably modeled after Håkonshallen in Bergen which was twice as long and twice as wide. A memorial to Audun, carved by Jørgen P. Solheimsnes from Jølster was erected on the site of the castle in 1960. Its motive is the baron's seal.
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.
