Charenza, also Karentia or Karenz, was a medieval Slavic burgwall on the island of Rügen in the Baltic Sea. It was the administrative centre of the Rani tribe and of the Principality of Rugia. Today, the remnants are called Venzer Burgwall. Charenza was not only the administrative hub of the Rani tribe, but also a religious centre with the temples of Rugievit, Porevit and Porenut. The main religious centre of the Rani, however, was Arkona on Wittow.
In 1168, King Valdemar I of Denmark and his archbishop Absalon captured Arkona. Charenza surrendered a few days later after negotiations with the Rugian princes Tetzlav and Jaromar I. The temples were destroyed, the princes agreed to become Danish vassals and the population adopted the Christian faith. In 1180, the administrative centre of the Principality of Rugia was moved to Rugard (today Bergen auf Rügen, just a few kilometres to the southeast).
In the 12th century, Charenza was mentioned by Saxo Grammaticus and Helmold von Bosau. The last records are from the early 13th century. When the Danish king raised money to build 12 churches on Rügen, one of them was the capelle nostre in Charenz, which in 1232 was granted the village of Gagern as a fief. In 1234, when the Rugian prince Vitslav I granted Lübeck law to Stralsund, the document was signed in Charenza. The last record mentioning Charenza was in 1237. In the 14th century, 'Gharense' was mentioned as belonging to the parish of Gingst.
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.
