Colonial Spanish Baroque Churrigueresque style facade — Metropolitan Cathedral of Mexico City. ::* The Metropolitan Cathedral is one of the most important historical buildings in Mexico City. Construction was started at the beginning of the eighteenth century, and was to continue throughout the next 300 years; this is why different influences can be detected in the architectural style, dominated by Spanish Renaissance and French Neo-classicism, along with a Baroque-touch to the rose sandstone roof. The Cathedrals five aisles are adorned with ostentatious-looking alters and elaborate engravings, and its floors are covered in marble.
