Plan of excavations of Imperial Palace of Maximianus Herculeus

This great palace with more than 8.000 m2 was built at 3rd century being occupied by Emperor Maximus between years 296 and 297.
The whole is rebuilt with opus caementitium reinforced with files of little ashlar and brick.
There are no remainings for imagine its distribution shape. A long semicircular and semiunderground corridor being 4 m. wide, more than 150 m. long and 55 m. radius was the main distributional element. Every chamber at the Palace -they were radial- gave access to this corridor. There were single exedrae or associated in groups from three to five. The semicircular corridor was crowned by a portico with columns -cryptoportico- illuminated by lucernarii. It also had the function of saving an existet break of level.
At its central axis there could have been a basilica. At both sides, other rooms and access corridors to other rooms, some ot them underground. The plan of a triconque chamber with an unknown finality is outstanding.
There are remainings of termae with three baths: the central one is decorated with wall paintings.
Preserved parts of the Palace are very spoilt since materials were used for new buildings. Recently, construction of a rail station destroyed a section of it.
