The current village of Rasiglia is dominated by the remains of the 13th century fortress, which later belonged to the powerful Trinci family from Foligno.
The fortress stands to protect the small rural village, placing itself along ancient mule paths and strategic transit routes. It was strengthened by the Trinci family between the fourteenth and fifteenth centuries, becoming a defensive bastion for the protection of the upper Menotre Valley and the important Via della Spina. During this period, Rasiglia extended its territory well beyond the borders of the village reaching around 400 in population, a size it maintained even after the Trinci family left.
As early as the 15th century, the settlement was structured as an important productive settlement, devoted to the exploitation of the abundant water of the Menotre river: mills, fulling mills and factories were erected. Over time Rasiglia increasingly assumed the role of artisanal center for the spinning, weaving and dyeing of wool and other fibers, including ones derived from plants.
