Three times larger than the Parthenon (about 12,000 square meters) and being the work of an intelligent architect of the 4th c. B.C., possibly Pytheus, the palace which we parallel to the "presidential house" of the ancient kingdom of Macedons, due to its public function as an administrative centre, and which constituted the model for all palaces of the hellenistic world, did not survive intact through the centuries.

Natural disasters of the 1st c. A.D. had it demolished, as well as subsequent earthquakes, the re-use of its structural materials by local inhabitants, and the natural wear of the course of time.

Therefore, only traces survive to date, which don' t allow us to imagine its original magnificence.

The architectural study for its consolidation and restauration, undertaken by the 17th Ephorate of Prehistoric and Classical Antiquities, not only clarifies the building's plan to the visitor, but also enhances its third dimension, through the restitution of the reclaimed original ancient structural material, complemented by new material, in points of focus where this is necessary.
