Restauração do pavilhão, cúpula metálica e luneta equatorial de 32 cm: conjunto arquitetônico do Museu de Astronomia e Ciências Afins (MAST)

MAST is a science and technology museum located in the grounds and architectural\ud complex belonging to the former Observatório Nacional in Rio de Janeiro. This complex, concluded\ud in 1921, comprises of 16 buildings, and was listed by the Artistic and Historic National (1986)\ud and State (1987) Heritage. This complex features three pavilions sheltering the equatorial\ud telescopes, typical examples of Architecture and Engineering buildings for Astronomic purposes.\ud Two of these pavilions, all of which are under the care of MAST, shelter the 21 cm and 32 cm\ud telescopes, plus a third, part of the National Observatory, which houses the 46 cm equatorial\ud telescope. The present study is the result of the work undertaken by MAST to preserve and restore\ud the historical buildings under its responsibility. Thanks to a partnership set up with the Vitae\ud Foundation, it has been possible to develop restoration work covering all aspects of the pavilions\ud (moving metal dome, building, scientific instrument), as well as the areas museography, with a\ud view to informing visitors about the restoration work undertaken. The project, based on the\ud historical research on the complex, was carried out by a multidisciplinary team over two years.\ud Each stage of the work was comprehensively photographed, including the intervention project\ud design, which was based on architectural surveys and the diagnosis of the complexs state of\ud repair, plus the restoration per se. This is a groundbreaking initiative in Latin America and will\ud serve as an example for future actions to be taken on historical buildings, especially those built\ud for scientific and technological purposes
