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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
