The municipality of Vigo is not only one of the major industrial cities in Galicia, but it is also one of the more important Roman centers of Pontevedra. Although within the city one will not find much Romanesque architecture, it can be seen a few kilometers away from the city center.

Vigo retains some interesting examples of Romanesque churches in southern Galicia: Santa Maria de Castrelos, Santiago de Bembrive, San Salvador de Coruxo...
