In the northeast of welcoming Portugal stands Bragança Castle (Castelo de Bragança)—a majestic example of medieval military architecture. This fortification, crowning the historic center of the city of Bragança, is located at an altitude of 800 meters above sea level and is considered one of the best-preserved castles in the region. 
The fortress is surrounded by powerful two-meter-thick walls with a perimeter of 660 meters. The ensemble is completed by fifteen defensive towers, dominated by the 33-meter Keep (Torre de Menagem). It is crowned with elegant Gothic windows, battlemented parapets, and four cylindrical watchtowers at the corners, giving the structure a rugged yet elegant appearance.
Of particular value is the interior space of the citadel, which houses the Domus Municipalis—the only surviving example of Romanesque civil architecture in the country. The castle not only served as a defensive shield on the border but was also the cradle of the House of Braganza, making it a key symbol of history and Portuguese national pride.
