These night shots by New York photographer Andrew Prokos capture some of the buildings designed by late Brazilian architect Oscar Niemeyer in Brasília (+ slideshow).

Andrew Prokos topped the Night Photography category at this year's International Photography Awards with the series, which documents buildings such as the National Congress of Brazil and the Cathedral of Brasília after dark.

"I became fascinated by Oscar Niemeyer’s buildings as works of art in themselves, and the fact that Niemeyer had unprecedented influence over the architecture of the capital during his long lifetime," said Prokos.

Niemeyer, who passed away last year, completed a series of civic and government buildings in the Brazilian capital over the course of his career, following the appointment of Juscelino Kubitschek as president in 1956.

As well as the congress building and cathedral, Niemeyer also designed the Palácio do Planalto - the official workplace of the president - as well as the National Museum of the Republic and Itamaraty Palace.

"I found the city fascinating from a visual perspective," Prokos told Dezeen. "At its best the Niemeyer architecture is elegant and inspired; at the other end of the spectrum there are structures that are straight out of the Soviet era."
