Minho

Minho is Galicia's longest river, with a length of 340 kilometers and a border with Portugal. It is the fourth largest river in the Iberian peninsula, behind the Douro, Ebro, and Tagus. The Minho is a river that provides water to vineyards and fields, generates hydroelectric power, and defines a part of the Spanish–Portuguese border. On old English maps, it is referred to as Minno.

The Minho's source is located north of Lugo, in Galicia, at Pedregal de Irimia. After about 73 kilometers, the river passes close south of the old Roman city's walls, discharging 42 m3/s on average, and flows south through canyons until the valley opens north of Ourense. From Portomarn to Frieira, the river has been tamed in reservoirs. Belesar, with 654 cubic hectometres, Peares, with 182 cubic hectometres, Velle, with 17 cubic hectometres, Castrelo, with 60 cubic hectometres, and Frieira, with 44 cubic hectometres, are the reservoirs along its length.

The story describes the oral history of Galician mythological beings who lived in the Rio Minho's basin, such as feiticeiras (witches) who lived in the same river, the Xarcos who lived in wells throughout the watershed, and fish-men who were amphibious and could live on land and in water.
