The first written mention of the castle in Olomouc is included in the Cosmas Chronicle in 1055. The king Wenceslas III, the last Přemyslid, also stayed at the castle and was assassinated here in 1306. In 1767 the young Mozart stayed in the house of the Chapter Provost on the castle grounds and composed Symphony No. 6 in F major here. Some of the recent celebrities who have visited the site are Mother Theresa or Pope John Paul II.
After being partially damaged during the Thirty Years’ War, the medieval castle grounds were reconstructed in the Baroque style over a period of almost one century. Today, there remains little visible evidence of the significance and power of this castle. As time went on, the castle was overbuilt with religious buildings and the Wenceslas cathedral.
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.
