The Lost Caves of St.Louis: a
History of the City's Forgotten
Caves by Hubert & Charlotte Rother
(144 pages)

The majority of the caves in this book were once used as cooling and storage areas for vats of beer and lager in the late 1800's to about the 1940's. Everyone has probably heard of the Lemp Brewery, but there were a few German immigrant families that started breweries in St. Louis, later to be bought out by other breweries or just go out of business. Some caves had sewer systems running within them and  one or two that were located under parks.
This was a fairly interesting book telling the location of the caves and a little of the history behind the caves.
