San Telmo existed in the 17th century. It was one of the earliest residential areas in BsAs (none). At that time, there lived a large number of dockers, brick factory workers and the working people of the lower classes, which was an industrial area. Later in the 19th world, Argentina exported a large number of wool and leather, which led to the development of the region. In 1871, yellow fever was prevalent here (recalling that I had an expensive yellow fever vaccination before I came to South America), and all the wealthy moved to La Recoleta. Later, these empty houses and land were used by the government to build many art galleries, museums and parks. In the middle of the last century, immigrants from all over the world poured into San Telmo. Bars, shops and Tango Show are increasing day by day. Gradually the air in San Telmo smelled like bohemian.
