Castle of Guimarães

The Castle of Guimarães dates from the 10th century and was built to defend its monastery from Muslim and Norman attacks, a construction ordered by Dona Mumadona Dias. The fortress needed an urgent renovation after a century, and the noblemen from the court of Count Dom Henrique destroyed what was left of the original construction and extended the castle's area and added 2 entrances, so it continued to be the official royal residence through the 11th and 12th centuries.
