The History of Santo Tirso is tied to itsbenedictine monastery. The town grew around it and, from 978 until 1834, it was a "couto" – a neutral area that belonged to the clergy.[3] Known initially as Santo Tirso de Riba de Ave, this city has been the capital of a municipality at least since 1833.[4] Its composition changed throughout the years, especially in 1998, when the nearby city ofTrofa created its own municipality, taking some of Santo Tirso's towns with it.[5]
Towards the middle of the 19th century, Santo Tirso spearheaded the industrialization of theAve Valley. One of the first textile factories in the region, the Fábrica de Fiação e Tecidos do Rio Vizela, opened inVila das Aves, part of its municipality, in 1845. This factory would become the largest of its kind in Portugal, with an area of about nine square kilometres and employing, at one point, over 3.000 people.[6]
