With the conclusion of remodeling and the construction of a new annex, it was reinaugurated on July 8, 2003, with the current denomination to honor its famous architect Oscar Niemeyer[1], who completed this project at 95 years of age.
[4] The museum features many of Niemeyer's signature elements: bold geometric forms, sculptural curved volumes placed prominently to contrast with rectangular volumes, sinuous ramps for pedestrians, large areas of white painted concrete, and areas with vivid murals or paintings.
The annex was completed and opened to the public in 2003, and the Novo Museu was renamed the Oscar Niemeyer Museum in the same year.
Constructed of reinforced concrete, the idiosyncratic,[2] 30-meter tall structure sits above a pool of water and is connected to the main museum building by a futuristic underground walkway.
[4] The annex contains a large spiral stairway among its levels, and the two diamond-shaped façades of the "eye" of the building are constructed of glass and steel and provide natural light to an exhibit space.
