Dayton Blockhouse Historical Marker

This building was a Military Blockhouse built at the Grand Ronde Agency by Willamette Valley settlers in 1856.
 U.S. troops were sent to the station the same year, and it was named “Fort Yamhill.”  By permission of the U.S. government, Fort Yamhill was moved from Grand Ronde Agency to Dayton in 1911, through efforts of John G. Lewis, a patriotic citizen. The structure was rebuilt on this spot as a memorial to General Joel Palmer, a pioneer of Oregon, Superintendent of Indian Affairs, founder of Dayton and donor of this park.
