The Archaeological Museum of Cheronia is located next to the Lion monument. It has three exhibition areas with archaeological finds from prehistoric to early Christian times, such as important works of pottery, parts of Mycenaean frescoes, coins and weapons from the tomb of the Macedonians and the polyandrium of the Thebans, burial objects from necropolises, sculptures from Livadeia and Cheronia.

Important exhibits include prehistoric objects of everyday use from the Neolithic Age and a collection of bronze vessels from the area of Orchomenos. Very important is also the replica of a house of the Neolithic period. In the hall of the historical period there are exhibited vases, a collection of coins, sculptures and objects from the practice of worshiping the gods. In the center of the hall stands a statue of Cybele from Livadeia. Of particular interest is the mosaic of the 3rd century BC, which has a geometric decoration and represents the personifications of the Epochs.

In the lobby, the visitor is informed about the life and work of the ancient Cheronian writer Plutarch.
