This collection comprises 40 pieces, such as cabinets, benches, musical instruments, instrument cases and sheet music. The instruments were offered to the Artistas de Minerva Philharmonic Society by the Calouste Gulbenkian Foundation in 1970, in exchange for the society's already ageing instruments. Maria Campina (1914-1984), a well-known pianist from Loulé, was the driving force behind this donation, which became part of the museum's inventory in 2000.
