Museu da Música da Arquidiocese de Mariana, Religious music museum in Mariana, Brazil.

The Museu da Música da Arquidiocese de Mariana occupies the Antigo Palácio da Olaria, also called the Palácio dos Bispos, a building from the first half of the 18th century on Rua Cônego Amando in the Chácara (São José) district. It forms part of the Centro Cultural Dom Frei Manoel da Cruz and holds a permanent exhibition of musical manuscripts, liturgical books, instruments and photographs.

The museum was founded in the 1970s to preserve the musical treasures held by the Archdiocese over centuries. The collection reaches back to the colonial period and continues through the 20th century, covering both compositions and original instruments.

The collection shows how closely music and religious life were connected in this region, through handwritten scores and instruments from several centuries. Visitors can see how church music shaped celebrations and worship across the Archdiocese.

The museum spans several floors, so visitors should wear comfortable shoes and allow enough time to move through all the rooms without rushing. Arriving early in the day is a good idea, as some areas have limited accessibility.

Some instruments in the collection date from the Portuguese colonial period and are rarely found in the southern hemisphere. They show the direct musical ties that once linked Europe and Latin America during that era.
