The Fort Sill Historic Landmark & Museum in Lawton, Oklahoma is a 19th century frontier army post consisting of 50 buildings and the grounds surrounding them. Fort Sill is perhaps best known as the home of Geronimo during his later years and is also an operating Army military base, home of the Field Artillery. Geronimo and Quanah Parker are buried in the post cemetery.
The Fort Rock, Oregon Catholic Church is part of the collection old buildings owned by the Fort Rock Valley Historical Society. The Fort Rock Valley area flourished briefly during the homestead period before World War I, but little remains in the area today.
