Since Molino Los Justos, going direction to Zagra, about 2 km away is with the castle of Pesquera, Tower or Fort of Pesquera.
It is a defensive complex situated in a Valley and situated on a rocky area that stands out on the right bank of the river Pesquera, tributary of the river Genil. This castle, which was part of a chain of towers, defended the valley of the river and the peasant population that lived on the cultivation of the fertile plains of the environment.
Its strategic importance increases under the Nasrid reign, in which the lands of Algarinejo become border with the Christian Kingdom.
The second construction phase of this Fort is Nasrid period, possibly a small fortified farmhouse that organizes a productive space through an irrigation ditch, farmland, and mill of cereals (Pesquera mill or feet of cloth). The old caliphate fortin is reinforced as well, in the early 14th century with a tower or cylindrical masonry watchtower, and the construction of a second line walled. It remains so until the 15th century that the fortress, after withstanding continual raids and periodic attacks, is occupied by the Castilian conquerors. Years later, following the establishment of the marquisate of Algarinejo, Pesquera Castle loses its functionality and is left up to the present day.
