This is one of the oldest chapels in the Algarve. It was founded in the 14th century as a chapel of pilgrimage, and was remodelled in the 15th century, possibly with the sponsorship of Prince Henry the Navigator, who came here to pray.
The façade, with a triangular gable, has an eye-window and an ogival doorway, and on the inside columns with abacuses and capitals with rope motifs.
It is interesting to note that the keystones of the vault and the capitals on the triumphal arch display symbols relating to the legend of Nossa Senhora de Guadalupe (Our Lady of Guadalupe).
