The building of the Museum includes, on an elevated ground level, the centrally placed entrance hall with a small shop and at the rear end, a small garden with a coffee shop. At the sides of the main entrance there is an elevator for vehicle access to the underground parking space, on the second level below ground, as well as the independent entrance of the final two floors, which were intended for residential use, as a means of additional income for the Museum organization.
A workshop for children lies in the first basement. The main halls of the Museum are located in three typical storeys, while a lecture hall and administration offices occupy the fourth floor.
In the interior, intermediate columns were avoided, to facilitate the free exhibition of collections. Their arrangement allows for a fluid circulation through them.
The austere character and the geometry of the forms, the main characteristics of the articles of the internationally known Museum collection, set in extent the architectural style of the building. The unadorned, cubic structure of the marble façade, as well as the details on the interior elements, reflect the aim to associate the contemporary building mainly to its prehistoric exhibits.
