The human occupation of the site where Beja rises today, goes back to prehistory, being even mentioned in the writings of Ptolemy. It was in Beja that Julius Caesar formalized peace with the Lusitanians.
In a combination of Romanesque, Gothic, Manueline and Mannerist styles, the medieval castle has in its tower the great symbol of Bejense pride. It is considered one of the most beautiful examples of military architecture of the Middle Ages in Portugal. Rising to forty meters high, it is the highest in the country.
