The heritage of the museum is a mirror of the systematic research carried out by the museum's experts during over 45 years of existence. The collection of the museum consists of a core of valuable pieces which have been gathered by passionate collectors since the beginning of the 20th century. The collection has been enriched by an impressive number of pieces from the systematic rescue researches undertaken in the rural areas in southeastern Transylvania, especially after 1990. If in 1985 the museum owned about 5,000 pieces, their number rises now to over 35,000. There have thus been created thematic collections, characterized by diversity, authenticity, representability, which illustrate the ethnological heritage specific to southeastern Transylvania.
