It also includes Sacred art from the early main church, archaeological findings such as Roman inscriptions, Castro culture ceramics and other collections.

In the book, Santos Graça presented the cultural issues of the community in a clear, elaborated and attractive way, including important and curious aspects such as social structure, ancestry, and change.

The First Regional Exhibition of Maritime Fishery of the Coast of Entre-Douro-e-Minho, held in Casino da Póvoa in October 1932, prompted the foundation of the museum by Santos Graça in 1937 in an attempt to preserve the practices and traditions of this community that were being rapidly lost without registration or academic studies.

The building was closed for works, but its collection kept being shown across Portugal and Europe, such as "Siglas Poveiras", winner of a 1980 International European Museum of the Year award, "Povoan costumes", "Archeology in the Municipality of Póvoa de Varzim"; "António Santos Graça - The Man and his Work", "Fishery, Sea Baths, Countryside life - a view of the community in times of change".
