Standing before this rosy Renaissance-style palace, you can easily imagine Eva Perón pontificating from the lower balcony. This is the Casa Rosada (Pink House), home to Argentina’s presidential offices. Construction began in 1862 on the site of Buenos Aires’ fort, and the building was painted pink shortly after. Visitors marvel at the picturesque coral hue without realizing the gritty fact behind it – at the end of the 19th century, ox blood added color and texture to ordinary whitewash.
