The Waikiki Natatorium War Memorial is one of Honolulu's most compelling ruins — a 1927 salt-water swimming pool and grandstand built as a living memorial to Hawaii's World War I veterans, slowly disintegrating in plain sight of the luxury hotels that flank Kaimana Beach. The structure, an Art Deco arch over a 100-metre open-air pool, has been closed since 1979.
It is worth walking past for the combination of its architectural ambition and its state of decay, which together tell a more interesting story than most intact monuments. The beach immediately in front — Kaimana Beach, also called Sans Souci — is one of Waikiki's quieter stretches, favoured by locals over tourists. Robert Louis Stevenson reputedly swam here when he lived nearby in 1893.
