Romanesque church with perfect back portal and rectangular main chapel, probably built by Count D. Henrique. Monument of great symbolism, both for the historical connection to the period of the foundation of nationality, and for the tradition of being here baptized D. Afonso Henriques. The main façade has a portal with two archivolts with a broken arch and smooth tympanum. Inside, there are graves of warriors who were linked to the foundation of nationality.
