Nestled adjacent to Lincoln Park Zoo behind a discrete entrance, the Alfred Caldwell Lily Pool provides a peaceful respite from city life. Alfred Caldwell was the landscape architect of the Prairie School who designed the pool in the 1930s on the site originally occupied by a Victorian garden in 1889. It went through a variety of permutations and had fallen into disrepair when it was taken over by the Lincoln Park Conservancy and restored over the past 20 years. The site includes a Japanese-style pavilion and a tiny waterfall. There are lots of frogs and turtles in the pond, and while most waterfowl congregation at North Pond across the street, some do make at least a temporary home here. The photos of a mother duck and her single duckling taken in late May 2017 are precious.
