Founded at the end of the last century, it displays archaeological collections from the municipality of Alcácer do Sal, from prehistory to the present day. The exhibited objects from the Iron Age and the Roman period are particularly noteworthy.

The museum space operates in the building of the former rice husking factory, located between the floodplain and the mangrove swamp. On the ground floor, in the boiler room, a film produced with former workers linked to rice production is shown, and tools are on display. On the other floors are the machinery, such as silos, bagging wheels, rice storage facilities, and rice gauges. On the top floor, there is a room where photographs are exhibited and which is also a space for artistic events, such as exhibitions or shows.

Considered the largest archaeological crypt in the country, it is located beneath the Castle of Alcácer do Sal, now transformed into the Pousada D. Afonso II. It presents traces of the Iron Age dating from the 6th century BC, as well as structures from the Roman period and the Islamic occupation, covering a considerable area. Medieval walls from the post-Reconquista Christian era were also found, based partially on Roman walls which, in turn, overlap older pre-existing structures dating from the Iron Age.

An old olive oil press, restored using traditional techniques and materials, has now been adapted into a museum. It is dedicated to the bread-making cycle, from sowing to baking. In addition to the permanent exhibition, the MET hosts temporary exhibitions.
