The Matriz Church, formally the Igreja da Nossa Senhora da Conceição, is Póvoa's main parish church and the most ambitious religious building in town. Construction ran from 1743 to 1757 in a sober mid-18th-century Baroque style — a single rectangular nave, plain stone facade, and a notable bell tower visible across the centre.
Inside, the gilded wood altarpieces and azulejo tile panels along the side walls reward a slow look. The church sits on Praça do Almada at the head of Rua da Junqueira, the city's traditional shopping street.
