Cradled on a granite outcrop above Guimarães, this rugged fortress is where Portugal’s story takes its first confident steps. The castle’s ring of towers, windswept battlements, and commanding keep frame sweeping views of the city that calls itself the nation’s birthplace. Wander the walls, then slip next door to a tiny chapel where a future king was baptized—and a country quietly began.

Historical Context
Raised in the 10th century by Countess Mumadona Dias to shield her monastery and settlement from Moorish and Norse raids, the Castle of Guimarães soon anchored a growing town. In the early 1100s it housed the young Afonso Henriques, who would proclaim Portugal’s independence after the decisive Battle of São Mamede (1128) nearby. The fortress assumed its present Gothic heft under Kings Afonso III and Dinis in the 13th–14th centuries, with thick granite curtains, eight towers, and a dominant keep. It endured sieges during the 1321–24 civil war and the 1383–85 Crisis, before artillery and shifting borders dulled its strategic edge. Reused as a prison, it decayed until declared a National Monument in 1881 and restored extensively between 1936 and 1940. Today it stands as a granite emblem of Portugal’s beginnings.
