Fort Henness (1855-1856) - A large stockade with two blockhouses first established in 1855 during the Washington Indian Wars by Grand Mound Prairie settlers in Thurston County, Washington. Named after Captain Benjamin I. Henness, Washington Territorial Volunteers. Abandoned as a fortification about 1856.
Fort Henness was built as a large stockade with two blockhouses on opposing corners enclosed by buildings that included a school for the children. The fort was reportedly occupied for 16 months by 224 people of 30 families during the emergency period of the Washington Indian Wars. Abandoned as a fortification about 1856.
Marker and fort plan sign at the fort site across from the Grand Mound Cemetery Entrance. A separate Masonic marker is also on the site but does not appear to be fort related.
