East St. Louis, Illinois, doesn't appear in many architectural guidebooks, but it should. Located just across the river from downtown St. Louis, the city boasts some of the most interesting architecture in the whole region. While much of the city's building stock has fallen victim to neglect and demolition, parts of East St. Louis' downtown remains intact, awaiting the day when prosperity returns to the city and the abandoned buildings find new use. Hopefully that day will come before the wrecking ball does.
