The current building of the Church of Santa Engrácia substituted previous churches dedicated to a martyr of the city of Braga, Saint Engrácia. The first church dedicated to the Saint was sponsored by Princess Maria, daughter of King Manuel I, around 1568. In 1681, building of the current church began after previous structures collapsed. The author of the new design was João Antunes, royal architect and one of the most important baroque architects of Portugal.
