Plaza de Mayo, Buenos Aires
Concierge.com's insider take:
The grassy Plaza de Mayo is B.A.'s village green. Originally laid out in 1580, the plaza was the site of the important uprising against Spanish rule that blew up on May 25, 1810 (thus the name). These days, the Plaza de Mayo plays host to countless tourists, a healthy pigeon population, and, every Thursday afternoon at 3:30 pm, Las Madres de la Plaza de Mayo, the activist-mothers who have protested the desaparecidos ("disappeared") of Argentina's 1976–1983 Dirty War for 20 years. At the Plaza de Mayo's center, one finds the Pirámide de Mayo, an obelisk commemorating the May uprising, and the square is bordered by the impressive Banco de la Nación, the old colonial Cabildo (town hall) and the Casa Rosada.
