An early building, perhaps built in the 14th century, it functioned at the time as a watchtower, but remodelled in 1573, it now has a single nave and a chancel, which despite their medieval origins show a strong Renaissance influence.

In the walled structure of Castelo Rodrigo, a bell tower was added, which originally had a hammer clock with granite weights.

Recently built in the 1940s, it houses the four-century image of Our Lady of Hope, who according to tradition accompanied Pedro Álvares Cabral on the voyage of discovery of Brazil.

Also referred to as the Castelo das Cinco Quinas (Castle of the Five Corners), due to the unusual shape of its pentagonal keep, it is believed to have been commissioned by King Dinis at the same time as he granted it its charter at the end of the 13th century. It served its military function once in a while, but also as a prison, having been abandoned and its walls dismantled for the construction of several houses in the town and the castle's square of arms began to serve as a cemetery, all this in the 19th century, and only in the 1940s of the 20th century was it possible to stop this degradation.
