Tidal Basin

Cooling Off in the Tidal Basin

Swimmers of all ages enjoy the Tidal Basin Bathing Beach in 1922.

The National Building Museum’s new indoor beach may be making headlines, but it’s not D.C.’s first seashore. For a period of time between 1918 and 1925, Washingtonians dipped into the Tidal Basin to experience some summertime heat relief. Now I know what you’re thinking: you couldn’t pay me to swim in that water today. But with a serious lack of public pools, and no air conditioning, citizens back then were pretty desperate.
