The Francisco Tavares Proença Júnior Museum, so named in honor of its founder, assumes, as main areas, Archeology, Decorative Arts with incidence in the Embroidery of Castelo Branco and Sacred Art.

The Museum's Main Hall is enhanced with the presentation of regular initiatives such as concerts, lectures, conferences, or other events in line with the Museum's mission.

The Francisco Tavares Proença Júnior Museum was created in 1910 by the archaeologist after whom it was named. Its mission is to "study and research, collect, document, preserve, interpret, exhibit, and divulge the cultural heritage that is part of its collection, with special emphasis on the Archaeology and Textile collections, understood as identity references, sources of scientific research, and aesthetic fruition. Its mission is also to publicize the local and regional heritage not represented in the Museum's collection and considered expressive of the identity of the communities in the region of influence of the Museum.

Integrated in the Network of Museums and Cultural Equipment of the Municipality of Castelo Branco, since September 1, 2015, under the Inter-administrative Contract of Delegation of Government Competencies, the Francisco Tavares Proença Júnior Museum has a temporary exhibition area, expanded and located in a privileged area, next to the Main Hall. Simultaneously, the Archeology exhibition component is being reinforced, as well as that of Sacred Art.

The D. Fernando de Almeida Library, created in 1985 following the donation of the bibliographical collection of the former director of the Museum, is now installed on the ground floor of the building to facilitate access, both to the general public, researchers and specialized public, but especially to citizens with reduced mobility.

Archaeology, the founding matrix of the Museum, now gains greater relevance, occupying the entire ground floor of the building, through the development of a coherent program of temporary exhibitions, while promoting the study, conservation and dissemination of the existing collection in the reserves. In addition to archaeology, the temporary exhibitions will also focus on textile art, sacred art, ethnography, furniture, and other areas related to regional culture. One of the museum's main sections is that of Textile Art, in which quilts from Castelo Branco predominate.
