1. The Rio de Janeiro Cathedral, also known as the Catedral Metropolitana de Sao Sebastiao, is a unique modernist building located in the heart of downtown Rio de Janeiro. Its unique design stands out in the city skyline, with its conical shape inspired by the Mayan pyramids of Mexico. The cathedral was designed by architect Edgar de Oliveira da Fonseca and construction was completed in 1979. It has a seating capacity of up to 20,000 people and is considered one of the most important religious buildings in Rio de Janeiro.

The interior of the cathedral is equally impressive, with stained-glass windows covering the entire space and four large bronze sculptures representing the Four Evangelists. The altar is also a standout feature, made of Italian Carrara marble and complemented by an impressive crucifix made of bronze.
