Terazije (Serbian Cyrillic: Теразије, literally Scales, more commonly known as "water balances" or "su terazisi" in Turkish) is the central square of the capital of Serbia. It is located in the Belgrade municipality of Stari Grad. The meaning of Turkish word "su terazisi" needs to be explained fully because the English term "scales" does not seem to be adequate. Terazije is probably more related to the word "reservoir" connected to the ancient Roman aqueduct which existed before the Ottoman times. Perhaps terazije is connected to a water distribution mechanism which existed here which lifted and distributed water further into the city. There is an underground natural and/or man made underground river in this area. "Water Balances" known as "su terazisi", were tower-like structures maintaining water pressure when conveying water to neighbourhoods at a high-level.
