The Igreja de Santa Maria do Castelo stands within the walls of the Castle of Alcácer do Sal, one of the most interesting examples of late-Romanesque architecture to survive in the south of Portugal, where the style is little represented.
The church was founded by the Order of Santiago after the reconquest of the town by King Afonso II in 1217, built on a site that had earlier held a pagan temple and then a mosque. For centuries it was the most important church in Alcácer and the principal meeting place of the town; municipal acts were once announced in its churchyard.
The church has three naves and a wealth of detail accumulated over the centuries: an eighteenth-century pulpit supported by a carved angel, gilded woodwork in the chapels, fine sixteenth-century ironwork, and walls lined with seventeenth-century azulejos, blending Gothic, Manueline and Baroque features. It faces the Roman forum, discovered in 1983, and stands as a layered record of the town's history.
