Santo Tirso Monastery

Monastery of Santo Tirso is a monastery located in the parish of Santo Tirso, municipality of Santo Tirso, in Portugal, that was of the Benedictine Order.

The monastery was founded in 978 by Unisco Godins, wife of Aboazar Lovesendes, first lord of Maia and ancestor of this family.

On 23 November 1097, count Henrique and his wife Teresa donated land, defining the boundaries, and other properties to Soeiro Mendes da Maia, a descendant of Unisco and Abunazar. Soeiro, in turn, on 23 March 1098 donated these properties to the Abbot of the monastery, Gaudemiro, making the monastery one of the richest and relevant in the country. It was awarded Bulls of protection by the Popes Innocent III and Honorius III.
