The cathedral is surprisingly small from the outside, but once you descend through the walkway, you emerge in the brightest and most spacious church you have ever seen. The floors and walls are made of white marble, with an expanse of glass overhead.
The altar is surprisingly sparse, all white marble decorated with a plain image of Christ on the cross. Sculptor Alfredo Ceschiatti designed the statues of the four apostles in front of the cathedral, as well as the angels suspended from the ceiling inside. You’ll spot his name on other sculptures around Brasilia, such as the figure of Justice in front of the Federal Supreme Court.
