The Archaeological Museum collects the most recently discovered materials in the city and in the area; It therefore constitutes, together with the Museum of the Faina Foundation, located on the opposite side of the Piazza del Duomo, a synthesis of archaeological knowledge about Orvieto. The rooms of the Museum collect, according to a topographical and roughly chronological order, the materials recovered during research in the necropolises and sanctuaries close to the city of Orvieto, as well as all the finds discovered following works carried out in an urban context, thus presenting themselves as formidable tool for understanding the social and cultural reality of one of the richest and most important centers in Etruria.

In the main room, ancient and new materials discovered from the northern necropolis of Crocifisso del Tufo are presented. Some notable funerary objects are rich in objects, both imported and locally produced, such as buccheri.

The adjacent room contains some grave goods recovered during the excavation in the necropolis of Porano , one of the smaller centers that surrounded the city on the cliff. The burials are of a high standard and in some cases have been embellished with wall paintings, among the few examples of such artistic expression, at least in internal northern Etruria. In an adjacent room, the reconstruction of the two Golini tombs, found at the end of the nineteenth century, is proposed, whose paintings, detached from the walls of the tombs, for obvious reasons of safety and correct conservation, have been relocated to their original positions.
