Niemeyer in Belo Horizonte.

"...and in 1940 received a call from Juscelino Kubitschek, mayor of Belo Horizonte, the capital of the state of Minas Gerais. Kubitschek, like Capanema, was among the enlightened politicians of the midcentury who embraced Brazilian Modernism. He asked Niemeyer to design a suburb called Pampulha. The complex Niemeyer built included an ovoid casino, a circular restaurant and a yacht club with a double-sloped roof. The centerpiece was a tiled concrete church, with a parabolic silhouette kind of like a roller coaster. Niemeyer had found his voice."
