Barillas is a town and municipality in the province and autonomous community of Navarre, in northern Spain. It is one of the many small municipalities that make up the rural landscape of this region of northern Iberia.
Navarre is an autonomous community in the north of Spain, and its municipalities are distributed across a varied terrain that includes river valleys, foothills and mountainous areas. Barillas shares the administrative status common to these towns, functioning as a municipality with its own local government.
As with many small Navarrese municipalities, Barillas is primarily known for its rural character and its place within the region's network of towns and villages. Detailed information about its population, history and landmarks is limited, and the town remains a minor entry among the municipalities of Navarre.
