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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
