Авенида де Майо
"Avenida de Mayo" links the "Casa Rosada" with the Argentine National Congress. On this avenue there are several buildings of cultural, architectural and historical importance, such as "Casa de la Cultura", the "Palacio Barolo" and "Café Tortoni". Underneath the avenue, the first "subte" (metro) line in South America, was opened in 1913. The avenue ends at "Plaza del Congreso", which features a number of monuments and sculptures, including one of Auguste Rodin's few surviving original casts of "The Thinker".
