This tour begins at the legislative end of Avenida de Mayo, in front of the National Congress, which will allow us to understand the internal affairs of Argentina before 1930, and to position this rich country, whose wealth was based on export of agricultural products, within a broader context of the international political scene at the beginning of the 20th century. We will move on to a stunning example of private prosperity, going hand in hand with the prosperity of the state: the impressive Palacio Barolo. The building will bring up the subject of presentation of the Argentine citizens a topic which leads us to the famous Teatro Colón. We then make our way to one of the most elegant districts of Buenos Aires Retiro, the destination of those who fled the southern parts of town to escape the yellow fever epidemic in 1871. We end with a stroll along Plaza San Martín.
