The monumental complex that houses the museum is built on the structures of the Roman theater and partly reuses its materials and walls. The Roman Theater (1st century BC) is used, during the Festival dei Due Mondi events, as a space for shows and concerts. The Museum hosts events related to school-work alternation and collaboration with the Municipality of Spoleto; themed guided tours; conferences (including the annual cycle, also scheduled for 2018, Telling the story); book presentations; concerts; temporary exhibitions (including, in 2017, artistic nativity scenes); laboratories and educational courses. Following the earthquake, safety measures were carried out on the structure. Through finds also coming from the most recent research, the first attestations of human presence in the area of the fortress and the historic center are documented, dating back to the Bronze Age, and the development of the settlement in the Umbrian phase, evidenced above all by the rich artefacts of VII -6th century BC of the Piazza d'Armi necropolis.
