The reconstructed archaeological remains of the Mithraeum are included into a cultural hub together with a contemporary art gallery and an educational area. The hub occupies a part of the Bloomberg building’s ground floor, also descending 7m below the modern ground level through a gallery, to reach the original Roman ground level where the remains are located.

The Starčevo culture emerges as the oldest Neolithic manifestation in the North-East Bosnia. So far it has been found only on the site in Gornja Tuzla, and in the Tuzla palafitte settlement. The prehistoric multilayer settlement in Gornja Tuzla is located on an elevated plateau on the right bank of the river Jala, in its upper reach, on the slopes of Majevica mountain. The settlement occupies a rather large area of about 15 hectares. The result of long-lasting continuous life in this settlement is presented in the form of cultural layer of thickness of up to 5.50 m.
