Oscar Niemeyer, the seminal modernist architect behind many of Brazil’s best known buildings, died on Wednesday in hospital in Rio de Janeiro.
Niemeyer, who continued to work on new projects until earlier this year, died just before his 105th birthday.
The architect is best known for designing the strikingly futuristic government buildings in Brasilia, the new capital of Brazil inaugurated in 1960.
As a student of Swiss master Le Corbusier, Niemeyer developed a style defined by stark concrete and sweeping curves.
He was awarded the Pritzker Prize in 1988 and went on to design more than 600 buildings around the world.
Brazil President Dilma Rousseff commented: “Brazil has lost today one of its geniuses. It is a day to lament his death. It is a day to acclaim his life.”
Major of Rio de Janeiro Eduardo Paes declared three days of mourning in the city, Niemeyer’s hometown.
