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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
