More than just Mexico City’s central post office, this early 20th-century palace is an Italianate confection designed by the Palacio de Bellas Artes’ original architect, Adamo Boari. The beige stone facade features baroque columns and carved filigree around the windows. Inside, the bronze railings on the monumental staircase were cast in Florence.
The small Postal Museum , on the 1st floor, is where philatelists can ogle a design of the first stamp ever issued in Mexico.
