Is it a bouquet of flowers? A sunburst? A UFO? No matter what you see in the 16 concrete pillars that make up this cathedral in Brazil’s capital, you have to admit it’s striking to look at. The Cathedral is dedicated to Mary and a column at the entrance depicts scenes from her life. But that isn’t the only artistic feature inside the building: there are four bells, a reflecting pool, and sculptures of angels that hang from a stained-glass ceiling.
