The Palácio dos Duques de Bragança is more than just ruins; it's a free, open-air museum that whispers tales of Barcelos' historical importance. Built in the 15th century, it was once the most opulent building in the city. However, the devastating earthquake of 1755 left it in ruins. Despite plans for demolition in the 19th century, the site was preserved and transformed into an open-air attraction.

Visitors can explore the remnants of this once-grand palace, situated conveniently between the main church and the river. The site offers a unique opportunity to connect with history in a relaxed, uncrowded environment. The presence of an attendant, even if just to lock up, adds a touch of local charm and reinforces the welcoming nature of Barcelos' residents, as noted by many visitors who found locals eager to help.

One of the most engaging aspects of the visit is the explanation of the 'Lenda do Galo' (Legend of the Rooster), a story deeply intertwined with Barcelos. Two slightly different versions of this famous legend are presented, offering a richer understanding of its cultural significance. The site also boasts lovely river views, making it a pleasant spot for a brief stroll and reflection.
