Mexico’s colonial history is best represented in one immense and ornate building: The Mexico City Metropolitan Cathedral. It was the first cathedral to be built in the Americas by the conquering Spaniards who wanted to show their domination and that of their culture and beliefs over those of the indigenous Aztec people. And they did so by building this large religious complex near Templo Mayor, the main temple where the Aztecs used to worshipped their gods. Today, the largest and oldest cathedral in Latin America remains a symbol of religious and colonial power, but it is also an impressive piece of architecture — and it is very much worth visiting.
