The Monastery of Leça do Balio also hosted the only royal wedding outside the capital, considered, over the centuries, as "cursed". On May 15, 1372, King D. Fernando married D. Leonor de Teles, an episode whose historical recreation we see here.

Neighboring the mouth of the river Leça, about a league north of the historic center of Porto, it is an original example of fortified religious architecture.

Religious, Romanesque and Gothic architecture. Fortified, oriented hospitable church, with a longitudinal plan of three naves of four sections, with inscribed transept, tripartite, staggered head, and quadrangular bell tower adjoining the main facade.
