The modernist architectural design of the church makes it one of the most fascinating churches in the world. It was designed in such a way to resemble the Mesoamerican step pyramids that were built during the Maya Civilization. The interior of the church is dominated by 4 immense stained glass windows which reach a height of 64 meters (210 feet) from the floor to the ceiling of the building.
Rio de Janeiro Cathedral is officially known as the Metropolitan Cathedral of Saint Sebastian or the “Catedral Metropolitana de São Sebastião.” It is dedicated to Saint Sebastian, a 3rd-century Christian martyr and the patron saint of Rio de Janeiro. The cathedral was completed during the 1970s and replaced an 18th-century church that is now referred to as the “Old Cathedral.”
