Final answer:
Cerro Catedral is not a capital city, but a ski resort in Argentina. The possible mix-up might be with Mexico City, which is known for the Catedral Metropolitana, or with Brasilia, the capital of Brazil, which features a significant cathedral designed by modernist architect Oscar Niemeyer.
Step-by-step explanation:
The city referenced in the question, Cerro Catedral, seems to be a misunderstanding. Cerro Catedral is not a capital city but rather a well-known ski resort in Argentina. If the question is regarding the capital of a country that has a significant cathedral, the answer might be Mexico City.
The Catedral Metropolitana in Mexico City is an important religious and historical landmark.
However, if you are asking about a modern capital city influenced by cathedral architecture, you might refer to Brasilia, the capital of Brazil, which features modernist architecture and is known for its landmark cathedral designed by Oscar Niemeyer.
