Amidst all the excitement over the Los Angeles Aqueduct’s 100th anniversary, we should point out that not every engineering marvel related to William Mulholland’s masterpiece was completed.  As displayed in the recently-closed show, Never Built Los Angeles, co-curated by this author and Greg Goldin, city officials and architect George A. Howard had planned a 220-foot-tall memorial to the aqueduct, located in the center of Exposition Park’s Rose Garden. Consisting of a fluted, classical column with a fresco-clad base, the memorial would be topped by a statue of “Miss Los Angeles,” who would continuously pour water into a moat below. Genius. Unfortunately World War I put a stop to the plan, and a modest fountain and lily pond, built in 1921, now stand on the spot.
