The Palace of Pella (Basileion of Pella) was built on a hill to the north of the city, in an exceptional location commanding a full view of the city, the sea, and the plain. The hill had steep slopes to the east and west, gentle access from the south, and was fortified on the north by a massive wall (3.30 m thick) equipped with towers every 33 m and monumental gates.

The Palace, covering an area of 70 stremmata (approximately 17 acres), consists of building complexes constructed on successive terraces descending from north to south and from the center toward the east and west. The terraces were created either through extensive leveling of the limestone bedrock or through the construction of powerful retaining walls and enormous embankments. The building complexes share common east?west and north?south axes and communicate with one another through stairways, gates, corridors, stoas, and peristyles.

Four of these complexes (I, II, IV, and V) formed the core of the palace complex. Buildings I and II shared a unified facade measuring 160 m in length, featuring two Doric stoas and a common propylon. These were the official spaces of the palace, with Doric peristyles, a large central courtyard, and spacious chambers where the political and social life of the kingdom was concentrated. Here, the king received diplomats and distinguished visitors, convened councils, administered justice, and fulfilled his role as high priest, as attested by the apses, altars, platforms, and bases for supporting bronze tripods and other votive offerings, as well as statues of ancestors, ancestral gods, and heroes.

Building IV, situated north of Building I, was intended for the residence of the king and his family. Building V comprised the integrated Palace Palaestra, which featured a large courtyard of 4.5 stremmata with a wooden peristyle. Behind the northern stoa stood a second internal stoa, necessary for athletic training during adverse weather conditions. At the rear, a series of rooms was discovered for exercise, education, recreation, and bodily care for the king and his officials, as well as for the royal pages and the young companions of the court, sons of the Hetairoi.

At a lower level west of the Palaestra and Building II, archaeologists uncovered a long covered corridor (xystos) with a stone staircase at its northern end, connecting with Buildings V and VIa. Buildings VIa?VIb constituted the facilities for the daily life and duties of the royal foster youths and cadets.

The complex Building III, erected during the reign of Antigonus II Gonatas over a massive unfinished stoa building of the early 3rd century BC, contained courtyards, stoas, corridors, rooms, storerooms, stables, workshops, and other spaces that were probably intended for technical and service personnel. Comparable large-scale buildings with similar installations were identified in the eastern and western sectors of the hill.

The dating of the first construction phase of the palace core to the reign of Philip II of Macedon (around the middle of the 4th century BC) is inferred from coins, pottery, the earliest stamped Laconian roof tiles, simas and Corinthian anthemion antefixes, marble lion-head waterspouts of the sima, and the Doric capitals of Buildings I and II. During the reign of Antigonus II Gonatas, numerous modifications were carried out in

the palace, possibly due to earthquake damage or in accordance with the king?s political program.

The palace was plundered and destroyed by the Romans in 168 BC, when the Macedonians were defeated in the Battle of Pydna, an event that marked the end of the Macedonian Kingdom
