This 16th-century Main Church is regarded as the first hall church in the Algarve.
It has three naves covered by ribbed vaults supported on very elegant columns.
On the façade, the highlight is the main doorway in the Renaissance style and the interesting semi-circular pediment, below which a niche with a statue of Nossa Senhora da Luz (Our Lady of Light) can be seen.
Interestingly, this church, which in some respects is so clearly in the Renaissance style, has a Manueline doorway on the southern side with small columns suggesting twisted ropes, evidence of its Manueline origin.
As regards the decoration on the inside of the church, the Mannerist altarpiece in the chancel stands out. A number of 17th and 18th century statues can also be seen, as well as a Manueline holy water font and an excellent statue of Nossa Senhora da Luz, dating from the 16th century.
