Following the republican 1910 revolution, the arrangement was overhauled and the museum's management stopped depending on the Academia Real (now renamed Academia Nacional de Belas Artes). By a decree of 26 May 1911, the collections were split up and two separate and independent museums created - the Museu Nacional de Arte Antiga ("National Museum of Ancient Art"), at the Palace of Janelas Verdes, and the Museu Nacional de Arte Contemporânea" ("National Museum of Contemporary Art") at the old location of the Academia's Galeria at São Francisco da Cidade (since renamed the Chiado Museum). The latter collection's cut-off date was roughly 1850, everything prior to that assigned to Arte Antiga.
