This early 16th-century Main Church was built on the orders of King Manuel.
The body of the church consists of three naves with four bays and a triple apse.
On the façade, the main doorway is an excellent example of the artistic style at the time of the Discoveries. It is a doorway with a semi-circular arch, with three archivolts decorated with plant motifs (leaves and stalks).
The collection of altarpieces deserves special attention, in particular the one in the chancel. It was made in the second half of the 18th century, and on it can be seen a painting of the Divine Saviour dating from the end of that century, by the Algarve painter Joaquim José Rasquinho.
Also deserving attention is the quality of the statues on the altars and the interesting panel of tiles in the Rococo style on the side walls of the church, depicting the Last Supper and the Washing of the Feet.
A final point of interest: next to the side door of the church is a small chapel which was created out of an old Muslim marabout.
