Castelo Mendo is a historic village with medieval roots, marked by two walls: the oldest, dating from the 12th century, surrounds the old town with its castle and the church …
Castelo Mendo is surrounded by a fortified wall with six medieval gates. Two wild boar sculptures stand to the left and right of the main entrance. The simple stone houses originally consisted of two floors. The ground floor housed livestock, while the upper floor served as a residential building. The extremely narrow streets made it relatively easy to defend the town, which was repeatedly a battlefield during the wars in which Portugal participated, especially against Spain.
