Portland had an unofficial world fair 120 years ago. I’m sad the little village and lake they built in northwest weren’t preserved, it looked nice.

120 years ago, Portland hosted a ‘World’s Fair’ that changed everything (then disappeared)
In 1905, the Lewis and Clark Exposition was held to commemorate the 100th anniversary of the Lewis and Clark Expedition, but, really, it was a way for city boasters to introduce Portland to the nation.
