Argentina is the eighth-largest country in the world. The highest and the lowest points of South America are also located in Argentina: At 6,960m, Cerro Aconcagua is the tallest mountain in the Americas while Laguna del Carbón, at 105m below sea level, is the lowest point in the Americas. Spring and fall often exhibit rapid temperature reversals; several days of extremely hot weather may be followed by several days of cold weather, then back to extremely hot.
The country is famous for tango dance and music. Its big, cosmopolitan capital, Buenos Aires, is centered on the Plaza de Mayo, lined with stately 19th-century buildings including Casa Rosada, the iconic, balconied presidential palace.
