Church located near the Fort of São Sebastião. One of its most important features is the rich interior decoration with tempera murals adorning all the elevations.
The main church has quite peculiar architectural details. The narthex is Renaissance, although quite altered, the chancel has a lunette vault and has Neo-Manueline elements in the parapet of the south facade.
An important work in the renovation of the town's military defense system, as evidenced by its proximity to the castle and the wall. An irregularly shaped fort with five bastions.
The outer wall, semicircular in shape, surrounded the medieval village and the so-called Old Castle. Today, only the remains of the castle with four turrets and a gate, the ruins of the Church of São Tiago, a 14th-century construction, and the Palace of the Mayors remain. The Castle offers a unique viewpoint over the Guadiana River, the village, the salt pans, and vast sea horizons.
Baroque religious architecture, vernacular. Small chapel, serving a reduced, rural population. It has a porch, single nave with a semicircular vault covering and quadrangular main chapel, with wood roofing.
