Part of the Museum’s mission is the safekeeping of the memory of the seafaring traditions of Cascais, maintaining a close connection to its surrounding environment and communities.

The maritime ethnography collection currently on display explores the practices and traditions of the fishing community and the clothes worn by local fishermen and fishwives; the traditional craft of fishing, illustrated through images of the present and of the past, audio and video records, archival material, such as photographs and documents; and different typologies of objects produced and used by the community, including traditional fishing vessels.
