The building that houses the museum follows the local traditional architecture and has been used as a teaching centre (Karytsiotis school), since the second half of the last century.

The prefecture of Astros conceded the building to the Ephoreia of Antiquities. In 1985, after a period of major repairs and conservation, the building was converted into a museum by the Ephor of Antiquities, Dr. Theodoros Spyropoulos. The museum's large courtyard was also converted into an archaeological park and exhibition.
