Information about the individual county histories
The individual county histories trace the establishment and evolution of each of the 36 county governments in Oregon. The histories include information concerning the creation and naming of the county; designation of county boundaries; location of the county seat; construction of the county courthouse; development of the county government; and description of the major industrial geographical, demographic, or historical features of the county.
Each county listed includes a courthouse address; clerk and trial court phone numbers; a map of Oregon showing the county's location; and an image of the courthouse. A "FunFact" for each county helps to interpret its history, geography, or other interesting feature. Links to county Web sites and scenic images are included as well.
