Brazilian architect Oscar Niemeyer has launched a book with photos and sketches of the churches and chapels he has designed over his long career.
"The Churches of Oscar Niemeyer" was launched Tuesday night in Rio de Janeiro.
The 103-year-old Niemeyer is responsible for more than 600 modernist projects around the world. They include the sweeping concrete structures that house Brazil's government in the capital of Brasilia, and U.N. headquarters in New York.
Niemeyer has won numerous awards, including the Pritzker Architecture Prize in 1988. He is still working.
