Housed in a house with traditional architecture in the region, it features ethnography collections and an interesting display of some traditional crafts.

The Museum is made up of three rooms with a total area of around 232 m2, dedicated to three themes: Earth, House and Water, representative activities of Murtosa. It displays objects linked to land preparation, harvesting, fishing, sargassum harvesting, food, spinning and weaving, transport, work and party clothing, household contents, lighting, miniature boats, religious objects and musical instruments.

The library bears the name of José Tavares Afonso e Cunha, a famed lawyer from Murtosa, who danated his books to the institution, so that they would be preserved. The heritage, a coillection of documents, is currently being digitalized.
