The Paço dos Duques de Bragança, built in the 15th century by the then-future duke Dom Afonso, shows elements of architectural styles common in the great manor houses and palaces of northern Europe. In the 19th century, it served as a military barracks. In the mid-20th century, after a period of disuse and abandonment, the palace was renovated and saw new life as a museum displaying items from the 17th and 18th centuries. From its various collections are pieces that document Portuguese contributions during the Age of Discoveries, while others narrate events in the Conquest of North Africa. Also in the holdings are a collection of arms from the 15th to the 19th centuries and furniture from the Post-Discoveries era.
In addition to the Palace’s role as a museum, its top floor also serves as an official residence of the President of the Portuguese Republic, should he decide to stay overnight in the north of the country.
It's located at Rua Conde D. Henrique, near the castle and the Afonso Henriques statue.
