By some counts Mexico City is the largest city in the western hemisphere, with over 20 million people. In Mexico, this capitol city is referred to as "D.F.", the Distrito Federal (Federal District), or simply as "México".
Downtown Mexico City is known as El Centro, or Centro Histórico.
The interior of the Palacio de
Correos de Mexico really is the palace of post offices, exquisitely
decorated with ornate brass and iron fixtures.
Monumento a la Revolución
The Monumento a la Revolución is a mix of styles — an enormous stone art deco
arch with a glass elevator rising to the center from the street below. Paying
for a ride to the top gives access to great views of Mexico City.
The sidewalk below contains a hidden fountain that periodically sprays surprise blasts of water.
