The main building of the Sines Museum and the Vasco da Gama House, located in the castle's inner buildings, were inaugurated in 2008. The main building houses an exhibition dedicated to the 20th century in Sines, as well as some archaeological collections. Some parts of the facilities dedicated to Vasco da Gama are of great interest, including his biography, the house where he lived, and his role in Portuguese maritime history.

This historic building was rebuilt in 1585 by King Felipe I and converted to cultural use in 1990. The museum includes pieces from the Paleolithic to the Baroque. Its main collection is the punic treasure of Gaio.

It was here that, at the age of 11 or 12, Vasco da Gama, along with three of his brothers, received his prima tonsure and became a member of the Order of Santiago. In the 18th century, the medieval church, already too small for the number of believers who wanted to attend Mass, required extensive remodeling, giving it its current appearance, typical of the Joanine Baroque.

This 16th-century chapel preserves the Manueline portal and inscribed tombstones on its main façade. On both sides are buttresses, topped by conical pinnacles, supporting the coffered vault covering the chapel's single nave. The walls are covered in 18th-century tiles. It has a single nave and a chancel with star-shaped vaults supported by corbels, Manueline decorative elements on the clasps, vault-flush corbels, and also on the portal.

A medieval castle, it has undergone several restorations over the centuries. All that remains of the original castle are the battlemented walls flanked by thick masonry turrets, the keep with twin windows, and the Alcaide-Mor Palace. On the ceiling of the fortress's armory, you can see interesting paintings of armor, war trophies, and the royal shield of King João V. Visigothic architectural elements are visible on the walls.

This square tower made with thick granite blocks (reaching two metres) was founded in the XV century by the 8th Count of Barcelos. The finishing is from the Renaissance period with cornice, gutter and merlons.

This is the old Linha do Dão, a railway line between Santa Comba Dão and Viseu, deactivated in 1988, which was transformed into this pleasant 49 km Ecopista, the longest Ecopista in Portugal.

Housed in the Solar de Santa Ana, this museum combines design, creativity, and excellent scientific content. Its permanent exhibition features collections of archaeology, history, ethnography, and sacred art.

This archaeological site consists of six schist panels, featuring hundreds of insculptural engravings, engraved using three different techniques: incision, pecking, and abrasion. The engravings depict a variety of motifs, including weapons (spears, daggers, and blades), agricultural tools (sickles), geometric designs (zigzags, lattices, circles, triangles), and podomorphic and filiform designs, dimples, and more. Some are more recent, likely executed during the Late Bronze Age and early Iron Age. It is classified as a Property of Public Interest.
