The Diocletian Aqueduct 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 Jadro River, 9 kilometres northeast from the Diocletian's Palace (today's Split 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 Diocletian 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 aqueduct was abandoned from 1932 when the modern water station Kopilica was built.
The aqueduct is currently being restored.
