Individual County Histories

The individual county histories trace the establishment and evolution of each county government in Oregon. This include information about 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 industrial geographical, demographic, or historical features.

Each entry 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.
