The Museum is housed in the Old High School of Atalanti which has been declared a protected monument. The three main rooms of the building and the main corridor are devoted to a display of archaeological finds from systematic and rescue excavations in the area of eastern Lokris and the north-east part of ancient Phokis.

In the main corridor are displayed stone objects, the majority of them grave stelai, with only a single statue-torso of a Roman general. From the grave stelai stands the type of limestone in the form of couch. The rest of the display, housed in the three rooms immediately beyond the corridor, is developed in chronological order. In the Case I vessels, figurines, and stone tools from Neolithic period have placed.
