The Castle of Bragança anchors the medieval citadel (Cidadela) on its hilltop above the city. Built in the 12th and 13th centuries, it is one of the best-preserved medieval fortresses in Portugal, with intact walls, towers, and a tall square keep. The keep has been converted into a small military museum with armour, weapons, and models of historical fortifications — modest in content but worthwhile for the views from the top.
The castle and the surrounding citadel walls are free to walk around. Inside the walls you will find a handful of houses that people still live in, giving the place an authenticity rare in preserved medieval towns. The setting is dramatic: from the battlements you look down over the modern city of Bragança and, on clear days, across the plateau toward Spain.
