Located just North East of the Conservatory which is right by the Lincoln Park Zoo, this Lilly Pond is worth a visit. Small, it was designed by Alfred Caldwell to give a prairie look to a small Lilly pond. Niagra limestone lines the walk and once you stop and view the pond, depending upon where you are standing you may view it is a running brook or as a pond. Stunning small pergola like building in prairie style often mistaken as a work of Caldwells friend Frank Lloyd Wright. If a docent is near, take a very informative walk with them. This pond is on the migratory path of over 5000 song birds.
