The Metropolitan Cathedral was the first monument to be built in Brasilia designed by the architect Oscar Niemeyer, and it is one of the main landmarks of the city. In the square that leading up to the cathedral, there are four three meter (9.8 feet) tall bronze sculptures representing the Four Evangelists, created by the sculptor Dante Croce in 1968. A 12-meter (39 feet) wide, 40-centimeter (16 inch) deep reflecting pool surrounds the cathedral's roof, helping to cool it down. Visitors pass under this pool when entering the cathedral. Try to visit the most famous building in Brasilia on a sunny day so you can see the beautiful contrast of lights.
