Interior view of the glass ceiling of the courtyard of the Postal Palace, Mexico City (Mexico). The building was built at the beginning of the 20th century, when the Post Office became a separate government entity in Mexico. Its design and construction back then was the most modern of the time. In the 1950s, the building was modified and its structure was affected, so when the 1985 earthquake struck Mexico City, this building was heavily damaged, undergoing restoration works in the 1990s.
