At its peak with a population of 40,000, Vanport was Oregon’s second largest city.

The story of Vanport city is an essential and often forgotten chapter in Portland’s history. Built in 110 days in 1942, Vanport was meant to be a temporary solution to Portland’s housing shortage during WWII. On Memorial Day in 1948, one of the dikes surrounding Vanport broke, flooding the city and wiping it out in less than an hour.
