The built-up area of Acharnes, in this southern part of the municipality, is continuous with that of the adjacent suburbs to the west, east and south.

[3] Acharnes was named after the deme Acharnae (Ancient Greek: Ἁχαρναί), a subdivision of Athens in classical antiquity.

[5] Acharnes is considered by some to be an unsafe place to live since it has an alleged high crime rate, usually involving drugs, theft and gang activity.

It was founded in 1977 by the local Greek Mountaineering Society, which also formed the Historical and Folklore Association in 1981, to which it bequeathed the museum in 1982.

The archaeological part of the collection was then separated from the historical and folklore material and was given to the Hellenic Ministry of Culture.
