El CentroBuenos Aires
is so grand that the El Centro (city center) district alone has more historic sites than many world cities. As you stroll, you'll view the iconic Obelisk, which overlooks the main Avenue 9 de Julio, and the Plaza de Mayo, where Evita addressed throngs of her followers from the balcony of the Casa Rosada. The churches are works of art—the Baroque Basilica of San Francisco is only one example—and even the office buildings are worth seeing (check out the elegant Palacio Barolo). In all, the architecture rivals that of any city in Europe.
