This mineralogy and palaeontology museum is host in the 17th century convent of the capuchin friars in Masullas, as a reminder of the vital work monasteries and convents did since the middle ages for the cultural and scientific development of the European countries.

The “i cavalieri delle colline” museum tells the story of the rural aristocracy of Masullas and Parte Montis, whilst also telling the story of the aristocracy in Sardinia. The museum’s mission also aims at improving the knowledge and fostering a dialogue with the young generations on the chronological evolution of justice and legality.
