Biescas (Spanish pronunciation: [ˈbjeskas]) is a municipality of northeastern Spain close to the border with France, in the midst of the Pyrenees in the province of Huesca.

The economic activities in Biescas have historically been traditional farming of cereals and of fodder for livestock, logging of forests, and bovine cattle and sheep for local consumption.

[5] At the beginning of the twentieth century, Biescas highlighted in the region for its wool traditional textile industry,[6] specialized in blankets and equipment for horses.

The oldest pieces of evidence from human presence in the Biescas municipality are Neolithic cists from the plain of Santa Engracia, which are estimated to be from the III millennium BC.

[9] In the sixteenth century, King Philip II ordered to fortify the Santa Elena canyon to protect his kingdoms of possible threats from beyond the Pyrenees.

In this context, on 6 and 7 February 1592 eight hundred people from Béarn invaded and occupied Biescas and the Tena Valley for eleven days, before being defeated in the Gorge of Lutherans battle.
