Built in the 16th Centuary it became the Parish church of Lagos in the Mid 18th c as the old Parish church was destroyed in the 1755 earthquake.
It is from these windows that Dom Sebastiao, the young King of Portugal is said to have roused his troops before the ill-fated Moroccan expedition of 1578 from which the King (and most of his troops) never returned.
The Santa Maria church is right next to the statue of Henry the navigator and also the church where he was originally buried before being moved to the monestayr at Batalha further north in Portugal and i think that makes it worth a visit even if you are a person like me who is not in to churches but loves portugese history.
This church is located overlooking the square where you'll find the statue of Henry the Navigator and the slave market. It's origins can be traced back to the 14th century but most of it dates from the 15th and 16th centuries although it was rebuilt following the 1755 earthquake and a fire in the mid-19th century. Henry the Navigator was buried here in 1460 before his remains were transferred to the Capela do Fundador in Batalha Abbey.
