The Castle of Guimarães is a medieval fortification located in the city of Guimarães, Portugal. It was originally constructed in the 10th century under the orders of Countess Mumadona Dias to protect the monastery of São Mamede from Viking and Moorish raids. The structure was later expanded and reinforced, becoming a pivotal site in the history of the Portuguese nation.
Regarded as the birthplace of Portugal, the castle is traditionally associated with the birth of Afonso Henriques, the first King of Portugal, who was born within its walls. The fortress features a central keep and seven square towers, representing a significant example of military architecture from the Reconquista period.
