It is located on Rua Dom Fernão, city and municipality of Bragança, in the North Region and sub-region of Terras de Trás-os-Montes, in the Northeast of Portugal, Northeast Trás-os-Montes
 
The Iberian Museum of Mask and Costume located on the main street of the Cidadela, opened on February 24, 2007, and is a space for disseminating traditions related to the Masks of the Northeast Trás-os-Montes and the region of Zamora (partnership between the Municipality of Bragança and the Diputación de Zamora).

The Museum consists of 3 floors that allow the visitor to come into contact, at any time of the year, with a multitude of festivals, characters and rituals where the mask plays the primary role of the festivities.

In addition to contact with the characters recreated by the 47 caretos on display, the museum allows the sound of traditional music to take the visitor to experience, through photographs and objects on display, the festivities represented in different locations during the winter period.

Its primary objective is to boost the culture of a region in the interior of the peninsula and highlight a unique cultural element “the masks” present in the well-known “Winter Festivals” which serve as a starting point for a whole set of ethnographic activities aimed not only at the regions involved in the project but mainly at those that are not directly linked to it.

The Winter Festivals are cultural manifestations transmitted over time orally, becoming customs, traditions and lifestyles specific to this cross-border region.

The ancient rituals passed down from generation to generation constitute an important and strong differentiating feature of one's own identity, representing a valuable cultural heritage that is limited to supranational territorial scopes.

In this museum, visitors can see masks, costumes, props and objects used in the “Winter Festivals” in Trás-os-Montes and Alto Douro and in the “Las Mascaradas de Invierno” in the Zamora region.

The Iberian Museum of Mask and Costume was born in a context of focusing on the theme of the mask as an identifying element of a region that still maintains its characteristics and traditions.

In this space the exhibitions deal with themes such as the Winter Festivals of Bragança, The Festival of the Child Jesus of Vila Chã de Braciosa, The Festa das Morcelas or Mocidade in Constantim, Festa do Chocalheiro or Velho de Vale de Porco, The Festival of the Boys of Aveleda, The Festival of the Boys of Verga, The Festival of the Kings of Baçal, The Winter Festivals of Parada de Infanções, The Festival of Santo Estêvão de Rebordãos, The Chocalheiro of Bemposta, The Feast of the Boy of Tó, The Feast of the Kings of Rio de Onor, The Feast of the Elders of Bruçó, Winter Feasts of the Province of Zamora and Carnival Feasts., Summer Masquerades and Winter Preparatory Rites.

The Educational Service of the Iberian Museum of Mask and Costume carries out visits and specific activities for school groups at different levels of education.
