The museum was funded in 1984 by a patronage of Fonsagrada neighbours. Currently, the town council and the high and elementary schools are part of the association. The museum houses etnographic, archaeological and contemporary art pieces.

The etnographic section presents a pantry, a smith's forge and a hearth. This section shows elements of rural trades, farm work, countryside and religiousness. Another important part is dedicated to migration, where the visitor can behold the memories of a local emigrant in Buenos Aires and Havana.

The archaeological section exhibits megalithic, castro and Romanisation pieces.

The folk architecture section displays constructive characteristics, materials and most usual house types, through scale models, plans and photographs.

The contemporary art collection, known as 'De ida e volta' (Roundtrip) is mainly composed of sculpture showcased all over the museum. The artists displayed are Ignacio Basallo, Mónica Alonso, Manolo Paz, Paco Pestana, Xoán Lamarti, Tereixa Gómez, Alvaro de la Vega, Manuel Patinha, Luís Borrajo, Fernando Villapol, Xurxo Oro Claro and Manuel Moldes.

One of the objectives of the museum is introducing the ways of life and work of a mountain region, which are on the verge of disappearing due to time evolution. The museum also aims to foster the visitor's reflection on the value of popular culture and changing times in rural sphere.
