Casa Número Uno, Photography museum in Centro, Brazil.

Casa da Imagem occupies Casa Número Um, a three-storey townhouse at Rua Roberto Simonsen 136-B, built in masonry in the 19th century over the rammed-earth foundations of a 17th-century house. Its brick walls, Riga pine window frames and French roof tiles date from that rebuilding; a 2009–2011 restoration added an anodised iron and glass skylight over the inner courtyard. It now holds the city's photographic collection.

The building dates from the second half of the 1800s and was later repurposed as a repository for photographs documenting the city's development. The collection preserves decades of visual records showing how São Paulo changed.

The museum helps people understand how São Paulo developed by showing different photographic collections that change regularly throughout the year. Visitors experience how photographs serve as windows into the city's past and transformation.

Casa da Imagem sits at Rua Roberto Simonsen 136-B, in the old centre of São Paulo, a short walk from the Pátio do Colégio and the Beco do Pinto. The building reopened to the public in November 2011 after restoration work begun in 2009, with free admission. It forms part of the Museu da Cidade de São Paulo, so confirm current visiting hours before setting out.

The museum maintains a digitalized collection that allows visitors and researchers to search and study many images online from anywhere. This access to rare historical photographs makes it valuable even beyond physical visits.
