Current Exhibits
See what’s on at the museum now!

We expect the Museum to be closed for several months, at least through October, as repairs due to the fire are completed. Indoor events at the Museum have been canceled for the next two months, at the least. While the weather is good, we will participate in outdoor events such as Third Thursday, and we will be setting up a booth at the Farmers Market on Saturdays. Volunteers are needed to staff these events. 

The Gresham Historical Society is a non-profit organization that is funded by memberships, grants, and fundraising events. To help with renovations from the fire and to make the building a safe place to store our collections, we have established the Gresham Historical Society Fire Account at the Gresham branch of Riverview Community Bank at 225 NE Burnside Rd. Donations can also be sent to PO Box 65, Gresham, OR 97030, or online at
