The Imperial Forums are a unique architectural complex in the world, the center of political activity in ancient Rome and composed of various buildings and monumental squares.
During antiquity, the Imperial Forums kept both their architectural conformation and their function intact, despite the expansions, fires, restorations and reconstructions that took place in about 150 years of history between 46 BC and 113 AD.
In 46 BC it was Julius Caesar who was the first to provide for the construction of a new square, initially considered as a simple extension of the Republican Forum. The Forum of Caesar was followed by the Forum of Augustus, the Forum of Nerva and the Forum of Trajan, certainly the most grandiose.
The set of these archaeological areas that extends between the Capitoline Hill and the Quirinaleconstitutes, from an urban planning point of view, an organic complex,
renamed in modern times of the "Imperial Forums".
