The entirely hilly territory of Murlo is situated between the Merse valley and the Arbia valley.
The Poggio delle Civitate must have been a lively and popular place even before the time of the Etruscans. This place that's particularly rich in minerals and with fertile soil, was chosen as a settlement, and is a very rare example of an "ancient factory", characterized by a large number of different productions.
More recent times have also left indelible traces in the history and territory of Murlo. One of the most important in its history is linked to the mines, created towards the end of the 9th century following the discovery of coal deposits in the locality of Pratacci. A village was formed, equipped with various furnaces. The productive settlement had a long life, and had a profound impact on the local economy, up until its end.
The archaeological museum is set up inside the histoic Bishop's Palace and the adjoining building. Here, numerous archaeological finds from the municipal area are kept. Highlights include grave treasures from the necropolis of Poggio Aguzzo (7th century BC), the materials found in the Etruscan site of Poggio Civitate, one of the most important discoveries regarding the population of Northern Etruria.
The excavations of Poggio Civitate, in fact, have brought to light the extraordinary remains of a stately residence, which testifies to two different construction phases (orientalizing and archaic), dating back to the 7th-6th century BC.
