As the official repository for the state’s military history, the Oregon Military Museum strives to provide visitors engaging exhibits and public programming that honors the military service and legacy of those who have called Oregon home.

Just off I-205, the Museum is a quick 30-minute drive from downtown Portland and Portland International Airport to the north, Woodburn to the south, or Sandy if coming from the east.

The Historic Park is open seasonally. In the future, the Museum’s main building, including the exhibit galleries and the Thomas E. Withycombe Research Library will be open year-round.

To bridge the gap, OMM will be providing education and outreach programming for the general public throughout the year. Check out our Events page for information about upcoming events happening at the Museum.
