Prehistory The Tui area was inhabited since prehistoric times. Evidence of this are the sites found during construction of the highway Vigo-Tui, on the border with Porriño, dating from the
Lower Paleolithic period which was the oldest in Galicia. The fertile valley of the Minho and its magnificent natural conditions allowed the Tudense territory to accommodate human settlement from the earliest times. The vestiges are from the Palaeolithic period (20,000 BC) in the fluvial terraces of the river Minho and Louro and from the Neolithic period (5,000 BC) are the Carrasqueira ax or megalithic monuments (Anta - Areas). The introduction of metallurgy (4,000 BC) left testimonies like the helmet of bronze Caldelas axes (now in the Tudense Diocesan Museum) or engravings of Randufe.
Middle Ages Its original local name,
Tude, was mentioned by
Pliny the Elder and by
Ptolemy in the first century AD. It became an
episcopal see no later than the 6th century, during the
Suevic rule, when Bishop Anila went to the second
Council of Braga. Later, in the
Visigothic period, it briefly served as the capital of a Galician subkingdom under king
Wittiza. After the campaigns of
Alfonso I of Asturias (739–757) against the
Moors, the town lay abandoned in the largely empty buffer zone between Moors and Christians, being later part of the "
Repoblación" (repopulation) effort carried out a century later, during the reign of
Ordoño I of Asturias (850–866). In the 10th century, it was raided by
Vikings, being abandoned and later re-established in its current location. In the 12th century it was taken from the Moors by
Alphonso VII. Today the town centre is near the Inn of San Telmo. On top of the hill, the cathedral (11th–13th century, and restored between the 15th and 19th centuries) preserves Romanesque elements in its main vestibule, and the Gothic period in the western vestibule. The town has two museums, one dedicated to archaeology and sacred art, while the other is the
diocesan museum. As a frontier fortress the town played an important part in the wars between Portugal and Castile. ==Economy==
