A Lenda do Tedo: it all starts in the early XI century when the area is still under heathen Moorish rule, with the king residing in a palace in Lamego, which wasn't taken until 1057 by Don Fernando I.

Don Tedo and his brother Rausendo, descendants of King Ramiro II de Leao (Leon) were strong and fierce caudilhos (warriors) who were the first Christians in this infidel land, and helped to build the first church in the area in the valley of Tevora from the trees of the Sousa. Don Tedo went to the king unarmed in order to come to some kind of truce, but was immediately imprisoned (tricky Muslims).

The king Alboacem had a beautiful daughter (they always do), Ardinia, who saw the most dashing Christian warrior and you've guessed it, they fell in love at first sight. She helped him to escape (of course). The furious king swore revenge against whoever had done this. The princess fled the palace with her "irma de leite" there they finally came upon an old monk named Gelasio, (conveniently) who proceeded to baptize them. Afterwards, the two girls went out to the prearranged place to meet Don Tedo on the banks of the Rio Tavora.

But, out of nowhere, appeared the king who got his revenge by killing Ardinia with a lance to the chest (snifle, snifle). Don Tedo heard of this evil deed and swore never to marry. He took her limp body and buried her in a mosteiro that he had built, which according to the book must be that of San Pedro das Aguias.
