In the two adjoining rooms are displayed representative examples of sculpture, mainly Roman and include relief grave and votive stelae with various subjects (horsemen, portraits, a funeral banquet, and deified mortals).
Other sculptures and inscriptions (all in Greek) provide evidence for the names of persons, cities, religious beliefs, social conditions and political circumstances.
There is a fourth room that houses a conserved mosaic from the remains of a Roman building at Kato Kleines.
More specifically, there are ceramic wares, objects for everyday use, materials for building houses, stone and bone tools, spindle whorls, and figurines.
There are also exhibits of the Byzantine and post-Byzantine period from the Lake Prespa area, chiefly the basilica of Agios Achilleios (capitals, chancel screen closure panels, chancel screen colonnettes), frescoes from various churches, parts of a wood-carved chancel screen from the hermitage of the Transfiguration (Metamorfosi), and an Vema door from the Church of Agios Athanasios in the community of Agios Germanos (16th century).
