The Chapels of Santo António and Calvário are a complex formed by two small buildings, located near the castle and the Church of Santiago. The chapels' collection includes two wooden images, one of the Holy Spirit and the other of St. Anthony.

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.

It is an 18th century Baroque temple with some of the unique characteristics of the militant church that emerged from the Council of Trent. Its interior has a remarkable set of historic tile panels that narrate episodes from the life of Christ and the Virgin.
