The museum is near the archaeological site. It was built in 1960 to house the excavated finds, and has operated as an archaeological museum since 1973. It has information panels and exhibits.

There are three rooms, the first containing the prehistoric finds and describing the layout of the ancient city, the second displaying the finds from the agora, the sanctuaries, and the cemetery, and the third with six mosaic floors from the archaeological site.

The exhibits include hydrias, mosaic floors, statues and statuettes, heads of statues, figurines, vases, and hoards of silver coins of the Macedonian and Hellenistic periods. All are from excavations in the wider area of Pella.

Among the most important exhibits are six mosaics from houses (Dionysos riding a panther, a lion-hunt, a griffin attacking a deer, a pair of centaurs, and vegetal ornaments), an interior wall of a house decorated with coloured plaster in the first Pompeiian style (2^nd cent. bc), a marble portrait head of Alexander the Great and a marble statuette of Alexander as Pan of the Hellenistic period, a small bronze statue of Poseidon attributed to the sculptor Lysippos, also of the Hellenistic period, hoards of silver coins of the Macedonian kings (5^th cent. bc) and of the Hellenistic period, a red-figure hydria decorated with a representation of Poseidon’s duel with Athena, dated to the late fifth or early fourth century bc, and a headless statue of a youth on horseback.

The information panels consist of topographical and architectural plans and drawings and photographs of the excavations, and there are also copies and casts of figurines and vases.
