The architectural heritage of Viana do Castelo combines different periods and influences, reflecting the historical importance of the city.
The Sanctuary of Santa Luzia is its most iconic landmark, standing out not only for its architecture inspired by the Sacré-Cœur in Paris, but also for its panoramic views over the city, the Lima River and the Atlantic. In the historic centre, Praça da República brings together some of the most emblematic buildings, such as the Old Town Hall and the Viana do Castelo Cathedral.
