Noia was a thriving commercial port during the Low Middle Ages, being at that time the third most important town of the bishopric of Santiago de Compostela, after the capital and the town of Pontevedra. From that era it had preserved a notable old quarter, with a series of late Romanesque churches.
The "Dia das Letras Galegas" (Day of the Galician Writers) was celebrated in honour of Antón Avilés de Taramancos in 2003 and María Mariño Carou in 2007, both born in this town.
