Postal Palace of Mexico City

The Palacio de Correos de México, also known as the "Correo Mayor" is located in the historic center of Mexico City, on the Eje Central near the Palacio de Bellas Artes. It was built in 1907, when the Post Office became a separate government entity. Its design and construction was the most modern at the time, including a very eclectic style which mixed several different traditions, mainly Neo-Plateresque, into a very complex design. In the 1950s, the building was modified in a way that caused stress and damage, so when the 1985 earthquake struck Mexico City, it was heavily damaged. In the 1990s, restoration work has brought the building back to original construction and appearance.
