The most important works of this kind have survived in Thessalonike. Particularly impressive is the Chortiatis aqueduct which conveyed water along a built conduit to a large cistern (reservoir) inside the Acropolis. The water was thence distributed, through a system of clay pipes, to smaller cisterns in the city. The cisterns were usually covered by a vault and coated with impervious hydraulic plaster.
Outside the west walls of the city several kilns have been excavated in which either vases or building materials (bricks, roof tiles) were fired. The largest technical project was the artificial harbour constructed by Constantine the Great in 322, which gradually silted up during the Turkish Occupation. In several parts of Macedonia wine-pressing installations and furnaces for smelting metal ores (Prilep) have been investigated.
