A series of places narrate the history and culture of the Gerrei. Armungia is a 'open-air' museum that includes the ethnographic museum of sa Domu de is Ainas, the blacksmith's workshop, the mineralogical museum, the Emilio and Joyce Lussu history museum and the Armungia nuraghe dating back to the 5th-4th century BC, which rises majestically in the centre of the village - an almost unique case of Nuragic architecture within an inhabited area - and which can be accessed from the ethnographic museum. The nuraghe, which gives its name to the village that developed around it, is the starting point in the itinerary of the museum system: walking the stone streets of the village you will discover all the cultural sites, each with its particular historical, artistic and archaeological value, all 'mirrors' of the local identity.
