The Aqueduct of Diocletian is an ancient Roman aqueduct near Split, constructed during the Roman Empire to supply water to the palace of the emperor Diocletian. The Aqueduct of Diocletian was constructed between the end of 3rd and beginning of the 4th century AD, at the same time as the palace.
The aqueduct took water from the river Jadro, 9 kilometres northeast of Diocletian's Palace, today Split's city centre, and brought water to the Palace over a height difference of 13 m. Another aqueduct took water from the same source to Salona.
The aqueduct was destroyed in the invasion of Goths in the middle of 6th century and did not work for thirteen centuries after that.
The first reconstruction of the aqueduct took place during the reign of the Austro-Hungarian Empire (1877–1880). The Diocletianic aqueduct was abandoned in 1932, when the modern water station was built in Kopilica, a peripheral area of Split. The best-preserved part of the aqueduct near Dujmovača (Solin) has a maximum height of 16.5 m and a length of 180 m.
References: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.
