Waikiki War Memorial Natatorium
This 1927 World War I monument, dedicated to the 102 Hawaiian servicemen who lost their lives in battle, stands proudly in Waikiki. The 100-meter saltwater swimming pool, the training spot for Olympians Johnny Weissmuller and Buster Crabbe and the U.S. Army during World War II, is closed as the pool needs repair. The city has commissioned a study of the natatorium's future while a nonprofit group fights to save the facility. The site is closed to visitors, but you can stop by and look at it from the outside. www.natatorium.org.
