Since 1998 the complex has been owned by the Provincial Council, previously belonging to the residents of O Mosquetín. There are two elongated buildings here. The closest to the river consists of three estancias and houses four mills. The other also has three rooms, housing the three fulling mills and three mills. It is a clear example of popular engineering, which takes advantage of the force of water, through a network of pipes, to move the stones of the mills and also to make the fulling mills work.
In the past, fulling mills were used to fulling mills, especially woolen blankets, and thus convert a fabric with a weak texture into one with a tight weave. The result was achieved by wetting the fabrics and beating them for a long time.
The age of this ethnographic group is unknown, and references can be found in the Cadastre of Ensenada (1753), Economic Description of the Kingdom of Galicia and Memoirs of Juan Antonio Posse.
