Dramatic colonnaded building, the Metropolitan Cathedral (©Alex Black/iStock/Thinkstock)
The cathedral stands on the site of Buenos Aires’ first church. The current structure dates from 1753-1822—its portico built in 1827—with a carved exterior telling the story of Jacob and Joseph. The 18th-century towers were never rebuilt and over the decades it has altered in architectural styles.
