CentroCentro

This guide to CentroCentro in Madrid follows the building from its 1907 groundbreaking, when Madrileños mocked the young architects' grand post office as looking more fit for God than the mail, through twelve years of construction to its 1919 opening as the largest post office on earth. You'll hear about the bullet scars still visible on its white facade from fighting in the square during the Spanish Civil War, and about the years after the letters stopped coming. Look up at that same facade as you ride the lift to the observation deck.
