Until a few decades ago, hemp was cultivated in the Aniene Valley and hemp was processed to make cloth, used for sheets, sacks, ropes etc.

The hemp museum was created by twin brothers, Settimio and Domenico Bernardini who collected antique equipments and tools for processing, hemp products and much valuable oral history. The whole process of cultivation and processing is shown: from soil preparation and seeding (which took place in March in tents near to the small streams of the valley) to the summer harvest, first the female plants and then the male. It then moves on to show processing, spinning, warping and weaving. Among the exhibitions of particular interest is a seventeenth-century loom still in use.
