Alfred Caldwell Lily Pool

This guide to Alfred Caldwell Lily Pool in Chicago traces the site from an 1889 Victorian hothouse pool built for tropical water lilies, through its 1930s ruin and landscape architect Alfred Caldwell's WPA-era remake into a miniature limestone gorge, to the early 1950s when the zoo turned it into a bird sanctuary. Caldwell called it a dead world when he came back to see it, decades later, speaking flatly to a newspaper reporter.
