The museum of the city is located inside the Sines castle.
The museum is small and free.
The main section of the Museum of Sines hosts, on the 1st floor of the Palace of the Military Governors (popularly known as the alcazaba), an evocative exhibition of the twentieth century in Sines.
Fishing, agriculture, commerce and the establishment of the Republic are some of the themes of an exhibition that, being permanent, is regularly reconfigured through dossier exhibitions on specific themes.
The exhibition “The Bosom of Tethys: Archaeology Collections of the Museum of Sines” is available for visit on the ground floor of the Palace of the Governors of the Castle of Sines.
Organized from the archaeology collections of the Museum of Sines, it shows objects that bear witness to the men who created and used them, both in their daily lives, to make better use of what nature offered them, and in the rituals and devotions with which they sought to give greater meaning to the phenomena they were confronted with.
It is also an invitation to discover the archaeological sites from which these pieces come, and to better understand a territory densely populated with remains, memories and legends.
The exhibition features objects from the Neolithic, Chalcolithic (Copper Age), Bronze Age, Iron Age, Roman and Visigothic periods.
Since July 12, 2021, the Museum of Sines has a new facility, a Vault, where its most valuable treasures are exhibited.
In the Vault, located on the ground floor of the Sines Museum, you can now visit the Treasure of Gaius, a treasure from the XVI century. VII a. C., of Phoenician origin, testimony to the commercial contacts and influences of the Eastern Mediterranean in the Iberian Peninsula, classified by the Ministry of Culture as of public interest.
Another highlight of the Casa-Forte is the collection of numismatics from the legacy of José Miguel da Costa, founder of the Museum. One of the richest in the country, this collection is the result of a collecting effort that fits into the great European tradition, which saw coins as one of the most important sources of knowledge of the history and art of the past.
The Vaulthouse also houses the “Treasure of the African”, discovered in Sines in 2012, composed of silver coins, some of which were minted in America, appearing in the necropolis of the church of São Salvador, associated with the skeleton of a possible African corsair.
The exhibition also shows two paintings by Álvaro Perdigão. Álvaro Perdigão (May 22, 1910 – March 10, 1994) was a renowned Portuguese painter. Born in Lisbon, Portugal, he devoted most of his professional life to teaching. His art shows a wide spectrum of colors – grey, blue, green, ochre, brick red, yellow, brown, red – scattered across the canvas in complexly textured spots.
His works include male and female figures, natural landscapes and still lifes. With his works, the artist expressed his vision and interpretation of the life of the common man in his everyday work. He died in Lisbon in 1994.
