The 16 concrete pillars are hyperbolic, meaning they are curved lines generated by straight lines.
The cathedral's stained glass windows were designed by Marianne Peretti and were replaced in the 1990s to restore original luminosity.
The structure is partially subterranean to avoid obscuring the skyline of the Esplanada dos Ministérios.
The bronze sculptures of the four Evangelists at the entrance are three meters tall.
The campanile (bell tower) houses four bells donated by the Spanish government.
The acoustics of the circular dome cause a phenomenon where a whisper at one point along the wall can be heard clearly at the opposite point.
The Catedral Metropolitana Nossa Senhora Aparecida is an expressionist structure designed by architect Oscar Niemeyer and structural engineer Joaquim Cardozo. Completed in 1970, the building features 16 hyperbolic concrete columns weighing 90 tons each, representing hands reaching toward the sky. The cathedral sits below ground level with an entrance through a dark tunnel that opens into a naturally illuminated, circular nave. The roof consists of 2,000 square meters of stained glass in varying shades of blue, green, and white. Alfredo Ceschiatti created the four bronze sculptures of the Evangelists located at the entrance. The baptistery is a separate, oval-shaped structure located to the left of the main entrance. Inside, three angel sculptures by Ceschiatti are suspended by steel cables from the ceiling. The floor plan is circular, measuring 70 meters in diameter, with the altar positioned in the center.
From the exterior, position yourself low to the ground to capture the curvature of the concrete pillars against the blue sky.
Walk through the dark entrance tunnel slowly to let your eyes adjust to the dramatic transition from shadow to the bright interior.
Look for the smaller, separate baptistery building to the side, which is often overlooked by tourists.
Visit on a sunny day to experience the full impact of the colored light filtering through the glass ceiling.
Do not attempt to touch the suspended angel sculptures or climb on the exterior concrete pillars.
Modest clothing is expected; avoid beachwear or revealing outfits out of respect for the religious space.
