Castelo do Queijo or Castle of St. Francis Xavier, built in the fifteenth century, is a small defensive fortification, located in the Square Gonçalves Zarco.
Since immemorial times it is said that the huge rock where the castle was built was a sacred place for Dragan, Celtic tribes who came to the Iberian Peninsula six centuries before Christ.
Composed of angular design, wide shot platforms and thick walls, with no towers, moats for the land, an impressive drawbridge, etc.. this entire ensemble makes this castle a beautiful work of art.
On the north side, is still the Portuguese coat of arms.
Set shortly after the City Park, this is one of the best spots in town to watch the sunset sun.
