Ateliê António Carneiro was built in the 1920s as the studio of artists António Carneiro (1872-1930) and his son Carlos Carneiro (1900-1971), key figures in Portuguese art, particularly in the Symbolist and Modernist contexts, respectively. António Carneiro's other son, the composer Cláudio Carneyro (1895-1963), also lived here.

The António Carneiro Studio's collection comprises around three hundred works by the artist, including: the final study for ‘A Vida’, a work from the transition from the 19th to the 20th century; the grand canvas ‘Camões reading the Lusiads to the friars of São Domingos’, self-portraits and a series of family portraits, as well as marine paintings, church interiors and panoramas of the city of Porto.
