Lore & Background
It flows through the town of Meira and reaches the lagoon Fonminhá in the municipality of A Pastoriza, which was historically (and wrongly) regarded as the source. The upper course has been declared a Biosphere Reserve. After about 73 kilometres, the river passes just south of the walls of the old Roman city of Lugo, discharging an average of 42 m³/s, and flows south through canyons until the valley widens north of Ourense.
Reader's Guide
The Minho River is significant as the longest river in Galicia and a key geographical feature defining part of the border between Spain and Portugal. Its waters support agriculture, particularly vineyards that produce notable wines such as Ribeiro and Vinho Verde, and it is harnessed for hydroelectric power through a series of reservoirs. The river's valley is a fertile agricultural region, and its lower course passes medieval towns like Melgaço, Monção, Tui, and Valença do Minho, which preserve fortifications and are national monuments. The river's etymology, according to E. Bascuas, derives from the Indo-European root *mei- 'walk, go', and it appears in ancient English maps as Minno. Oral tradition includes stories of mythological characters such as feiticeiras (witches), Xarcos, and fish-men living in the river basin.
