Waikiki Natatorium War Memorial

The Waikiki Natatorium War Memorial is a World War I living memorial on Oahu, Hawaii, USA. It is a salt-water swimming pool built in the ocean on Waikiki’s San Souci beach.

History of the Natatorium

The memorial was designed to honor the ~10,000 men and women from Hawaii who served and the 101 who gave their lives during World War I. The opening ceremony took place on 24 August 1927.

The Waikiki Natatorium War Memorial is currently closed to the public due to disrepair and neglect by the local and state government. It has been shuttered since the 1980s, and there is an ongoing effort to try and preserve the memorial and the legacy of those who served, sacrificed.

Documentary ‘The Tank’

The most recent effort is a documentary film The Tank which chronicles the role of the Natatorium in the lives of thousands of Oahu children and families, as well as the world-class swimming culture that was spawned by olympians and local folks.
