Cuauhtémoc (Spanish pronunciation: [kwawˈtemok] ) is a borough of Mexico City. Named after the 16th-century Aztec ruler Cuauhtémoc, it contains the oldest parts of the city, extending over what was the entire urban core of Mexico City in the 1920s.
Cuauhtémoc is the historic and cultural center of Mexico City, although it is not the geographical center. While it ranks only sixth in population, it generates about a third of the entire city's GDP, mostly through commerce and services. It is home to the Mexican Stock Exchange, the important tourist attractions of the historic center and Zona Rosa, and various skyscrapers, such as the Torre Mayor and the Mexican headquarters of HSBC. It also contains numerous museums, libraries, government offices, markets, and other commercial centers, which can bring in as many as 5 million people each day to work, shop, or visit cultural sites.
