Walk down to the tide line at Seaside, Oregon, and you can see it - a relic of the 1920s, still drawing saltwater from the Pacific Ocean, still doing the job it was built for almost a century ago. What that job serves has changed. When the pipe was installed in 1924, it filled a natatorium - an indoor saltwater swimming pool where vacationers soaked in heated ocean water while spectators watched from balconies above. The Great Depression killed that business within a decade. The building tried on new identities: salmon rearing facility, wrestling venue. Nothing stuck until 1937, when someone had the idea to fill the old pool with marine life instead of swimmers. The Seaside Aquarium opened on May 25 of that year, making it the oldest privately owned aquarium on the West Coast. The pipe kept pumping. It pumps still.

It had been adrift for two years, swept from Japan by the catastrophic tsunami that followed the 2011 Tohoku earthquake. Inside the hull, impossibly, fish were still alive - trapped in the water that had col...

Seaside Aquarium: Salt Water and Staying Power

Wed, 18 Mar 2026 00:00:00 GMT

Photo credit Bobjgalindo, CC BY-SA 4.0. The Seaside Aquarium has survived by staying small and staying put. It has no corporate parent, no expansion plans, no ambitions to rival the big aquariums in Newport or Portland. It occupies the same building it has always occupied, draws water through the same pipe, and charges...
