The Botanical Building was constructed for the 1915-1916 exposition. The most striking feature about this structure is the gigantic wooden beam roof construction. San Diego’s perfect climate allows it to be such an open construction.
The Lily Pond was also built for the 1915-1916 fair. During World War II the pond was used as a rehabilitation pool for wounded soldiers. The lawns around the Lily Pond are very popular for sitting on the grass and relaxing. The pond is home to water lilies as well as large and colorful koi fish.
