Buenos Aires City is Argentina’s the most important city and one of the ten most populated of the world. In colonial times, Buenos Aires was an important commercial centre and almost all European ships would arrive there. Buenos Aires is still an important international centre for commerce and tourism. The area of Buenos Aires is 200 sq. km, its natural borders are River Plate and the "Riachuelo" (The Brook). Its climate is temperate and humid.

Its historical centre shows the contrasts of a big city. Past and present melt when one sees its religious temples, monumental buildings and recycled houses.
Four itineraries cover Buenos Aires City.

The first one is the HISTORICAL AXIS of the city, that runs due west from Plaza de Mayo (May Square) to Plaza del Congreso (Congress Square). Colonial, Spanish, European and Porteño styles are present in every single block. In the historical axis the tour starts in Plaza de Mayo that is nearby some important places: the Cabildo (Town Hall), the Cathedral, the Pink House (or Executive Office Building), the Legislature Building, the National Bank and the Plaza de Mayo proper. Then it’s time to go along Avenida de Mayo (May Avenue), the best reference to the city’s Spanish tradition to get to Plaza del Congreso.

The second itinerary is the HEART OF THE CITY, which includes what Porteños call “The City”, Plaza San Martín (San Martín Square) and Plaza Lavalle (Lavalle Square). “The City’s” financial rhythm is visible in Florida St.. Plaza San Martín, with its stately architecture and surrounded by European-styled palaces, is a haven. Plaza Lavalle leads to the Obelisk, symbol of the city, in 9 de Julio Av. and to the mythical Corrientes St..

The third itinerary is called TRACES OF THE PAST and includes the Block of the Lights and San Telmo, Buenos Aires’s most traditional neighborhood. San Telmo and the south of Monserrat are the oldest areas in the city. Their rich architecture and its Bohemian image are their main characteristics. The Block of the Lights is located in Monserrat district, where the “porteña” elite lived in the XIX century. Traditional Churches, Art and History museums and the old mansions of the then upper class mix there. San Telmo still has an old appearance, with its colonial houses and cobbled streets. San Telmo also has many churches, museums, antiques houses and fairs.

The fourth itinerary is SOUTHERN COAST AND PUERTO MADERO, Buenos Aires’ new face. The city faces the Rio de la Plata (River Plate) with its reformed look: the ecological reserve in Costanera Sur (Southern Coast) and Puerto Madero’s recycled docks that have become a very sophisticated gastronomic and recreational area.

Puerto Madero is Buenos Aires’ old port that is nowadays a residential and commercial area that links the centre of the city with the southern coast. One can visit its four docks, its lately recycled floating museums and the immigrant’s old disembark area. In the southern coast that Buenos Aires’ magnificent past survives in its boulevards, its buildings, its esplanade and its pergola.
