Once San Telmo, the oldest district in Buenos Aires, used to be the place, where the elite lived. In 1870, during the epidemic of yellow fever, the aristocracy left San Telmo and moved to the north of the city. A lot of emigrants rushed into this area and the houses of the rich were turned into «conventillos». In 1970 some of these historical buildings were restored. Nowadays, San Telmo is a picturesque area with antique shops, Colonial architecture and plenty of ancient churches (for example, San Pedro Telmo). Some streets are still cobbled. Visiting San Telmo on Sunday is a great idea, because on this day Plaza Dorrego, the heart of the district, turns into a flea market and the streets are crowded with jugglers and tango dancers. Travellers, who are fond of tango, should definitely visit famous tango cafes, such as El Viejo Almacén, Michelangelo, La Casa Blanca and La Casa Rosada.
Puerto Madero is located on the bank of the Rio-de-la-Plata. This is a former port area that was built in 1888-1897. Currently, this is the most modern entertainment area in the centre of the city, where one can still feel the charm of the port. Nowadays, former docks have been turned into restaurants and shops. If you want to have a nice walk, eat tasty food and enjoy wonderful shopping, Puerto Madero is definitely the place you need.
