Manning–Kamna Farm

The Manning-Kamna Farm is a private farm adjacent to Hillsboro in Washington County, Oregon, settled in the 1850s. Ten of its buildings, constructed between 1883 and 1930 and including a cross-wing western farmhouse, barn, smokehouse, pumphouse, woodshed and privy, were added to the National Register of Historic Places in 2007 as an example of a farm from the turn of the twentieth century in the region. The farm was used to grow seed crops, including rye grass and vetch, until the 1950s.
