TUY, a city of north-western Spain, in the province of Pontevedra, on the right bank of the river Miño (Portuguese Minho), opposite Valença do Minho, which stands on the left bank in Portuguese territory. Pop. (1900), 11,113. Tuy is the southern terminus of the railways to Santiago de Compostela and Corunna, Valenga do Minho is the northern terminus of the Portuguese railway to Oporto. Near Tuy rises the Monte San Cristobal, whose far-spreading spurs constitute the fertile and picturesque Vega del Oro. To the east is the river Louro, a right-hand tributary of the Miño abounding in salmon, trout, lamprey, eels and other fishes; and beyond the Louro, on the railway to Corunna, are the hot mineral springs of San Martin de Caldelas. Tuy is a clean and pleasant city with well-built houses, regular streets and many gardens. The cathedral, founded in the 12th century, but largely restored between the 15th and 19th, is of a massive and fortress-like architecture. Its half-ruined cloister and noble eastern facade date from the 14th century. There are several large convents and ancient parish churches, an old episcopal palace, hospitals, good schools, a theatre, and a very handsome bridge over the Miño built in 1885. The industries of Tuy include tanning, brewing, the distillation of spirits and the manufacture of soap. The city has also a brisk agricultural trade.
During part of the 7th century Tuy was the Visigothic capital. It was taken from the Moors by Alphonso VII. in the 12th century. As a frontier fortress it played an important part in the wars between Portugal and Castile.
