The permanent exhibition of the Archaeological Museum of Eretria has been operating in its current form since 1991. It contains finds from the wider area of Eretria that chronologically cover the time periods from the Early Bronze Age to the Roman Years. These are large archaeological thematic units, such as ceramics, sculpture, silver and goldsmithing, weaponry, which give an indicative picture of the culture that developed in this area and its inhabitants. The best-known exhibits to the general public, much more to the scientific community, are the small clay centaur from the cemetery of Lefkanti, the earliest representation of this mythical creature, and the sculptural complex of Theseus with the Amazon Antiope from the west pediment of his Late Archaic temple of Daphniforos Apollo in Eretria.
The reasoning behind the organization of the exhibition was based on the one hand on the overall presentation of the culture that appeared and developed in various stages in this region of Evia, starting from the Bronze Age and reaching the Roman period. On the other hand, particular emphasis was given to specific thematic sections (daily life, burial life, religious life, sports life), which help the visitor of the exhibition to see from particular angles the way of life of the inhabitants and to understand their technical skills and cultural development. The provision of observational material and information boards clearly explains the role of Eretria and the surrounding area in relation to the history of the island.
In the vestibule of the museum inscriptions are presented, in the first room prehistoric finds, in the second room the sculptures of the temple of Daphnephorus Apollo, as well as objects of daily and private life, sports and religious life and funerary life, while in the courtyard of the museum there are architectural members, resolutions and other inscriptions.
