Which cathedral in Brazil is shaped like a crown of curved concrete ribs designed by Oscar Niemeyer?

Brasília Cathedral is shaped like a crown of curved concrete ribs designed by Oscar Niemeyer.

The cathedral, formally the Metropolitan Cathedral of Our Lady Aparecida, was designed for Brazil’s new capital. Its hyperboloid structure uses sixteen concrete columns that curve inward and meet above the main worship space, creating a dramatic crown-like outline.

Construction began in 1958 and the cathedral was dedicated in 1970. The building’s glass walls and underground entrance produce a striking contrast between the dark approach and the bright interior.

Brasília Cathedral is sometimes confused with other modern Brazilian churches, but its distinctive crown form and association with Oscar Niemeyer make it especially easy to identify.
