San Telmo is the smallest but probably the most picturesque and historic part of Buenos Aires. Here you will find a large number of old buildings dating from colonial times. Some of them are in a pretty good condition while others are going to seed. The barrio was once the city's upper-class district but yellow fever had driven away most of the former denizens in 1871. Some of the old mansions can tell you stories of a time long gone just by the fading elegance of their facades. I love this old building in the picture in particular for its decaying charm and fading beauty.
