Explore the Oregon Military Museum
The Oregon Military Museum (OMM) proudly introduces four new exhibits alongside our 6-acre Historic Park. Together, these experiences honor the interconnected lives, service, and legacy of Oregonians in military service.
Spanning centuries of innovation, conflict, and community impact, OMM offers a powerful introduction to Oregon’s role in military history at home and around the world, connecting the past to the present to inspire future generations.
Inside the Museum
The main building, formerly the 1954 Clackamas Armory, features four new permanent and rotating exhibits.
We Are Oregon (Main Gallery)
Discover the region’s deep military legacy from pre-statehood to the present. This flagship exhibit highlights the people, technologies, and defining moments that connect Oregon and its communities to local, national, and global history.
Small Arms, Big Impact (Weapons Gallery)
Explore more than 170 firearms spanning over 400 years, from the 1600s through the Global War on Terrorism. This gallery features selections from one of the largest publicly accessible small arms collections west of the Mississippi River, tracing technological innovation, conflict, and the personal stories behind the weapons.
History in Art: Selections from the OMM Collection (Temporary Gallery)
Experience military history through the eyes of service members. This exhibit showcases artwork by and about U.S. service members, revealing how provenance, personal perspective, and visual detail deepen our understanding of history and our connection to the objects themselves.
Hall of Valor
This exhibit commemorates the 13 Medal of Honor recipients accredited to Oregon. Interactive displays share their portraits and stories, while also recognizing 21 additional recipients with Oregon ties who are accredited elsewhere. The exhibit also honors two individuals who received British and civilian equivalents and includes a complete list of Oregonians awarded the Service Cross, the nation’s second-highest military decoration.
Explore the Historic Park
The Oregon Military Museum’s 6-acre Historic Park at Camp Withycombe offers visitors of all ages an immersive open-air experience. Guests can walk through history, engage with hands-on interpretation, and view remarkable artifacts that tell the story of Oregon’s military service.
Anchoring the Historic Park are two of Camp Withycombe’s original buildings, both constructed around 1911.
Battery A Field Artillery Horse Barn
Step inside this historic officers’ horse barn to learn the story of Battery A, the predecessor of today’s 218th Field Artillery Regiment. Here, you can walk among examples of artillery used by, and against, the soldiers of this Oregon unit.
Quartermaster Storehouse
Ever wonder how an army gets its supplies? Discover the vital role of logistics from the early years of the Oregon National Guard to the present day. Interactive displays invite visitors to walk into a full-size Sibley tent and try their hand at loading a supply wagon.
Outside, visitors can also explore the Tracked Vehicle Display. From the World War II–era M7 Priest to the modern M1 Abrams tank, guests are invited to view five tracked vehicles up close.
For visitor safety and preservation purposes, climbing on vehicles is not permitted.
