Francisco Serrador Building, Art Deco building in Cinelândia district, Rio de Janeiro, Brazil.

The Francisco Serrador Building is a 23-story Art Deco structure in downtown Rio de Janeiro featuring copper panels and marble details throughout its entrance hall. The construction displays the hallmarks of the style with refined materials and a vertical composition typical of the period.

The building was completed in 1944 as one of Latin America's largest hotels of its time. Over the following decades, it changed hands several times and gradually transformed into office and administrative spaces.

The first-floor nightclub was named Night and Day after Cole Porter's song. In the 1960s it drew politicians and celebrities to the Hotel Serrador, and after the hotel closed in the 1970s Petros kept the club's interior unchanged for years.

The building is easily accessed from Cinelândia Square, which is well connected by public transportation. Visitors should note that the structure now serves as an administrative headquarters, so some interior areas may have restricted access.

In February 2015, Rio's city government listed the building's rooftop, its original architectural elements and the decorative features of its facade, so the protected area covers more than the roof alone. The building has 22 floors and a circular shape, unusual for Rio's downtown blocks.
