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. d'Este commissioned a prominent classical scholar, Pirro Ligorio, who had studied the Villa Hadriana and other Roman sites the vicinity, to plan a new villa and garden which would exceed anything the Romans had built. He obtained an abundant supply of marble and statuary from the ruins of Hadrian's villa.
The construction began to slow in 1569, probably due to the financial difficulties of the Cardinal. He spent more and more of his time in the villa, reading and meeting with the leading poets, artists and philosophers of the Renaissance. In 1572, the Cardinal died in Rome, and was buried in a simple tomb in the church adjoining the Villa.
With the death of Ippolito in 1572, the villa and gardens passed to his nephew, Cardinal Luigi (1538-1586), who continued work on some of the unfinished fountains and gardens, but struggled with high maintenance costs. After his death in 1586 Cardinal Alessandro d'Este (1538-1624) carried out a major renovation of the gardens and water systems, as well as building a new system of fountains in the lower garden.
The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
