The Fort Still National Cemetery was dedicated in November 2001, and is placed on land that was originally part of Ft. Sill Military Reservation, and before that, Indian Territory. The Ft. Sill National Cemetery was the second to be constructed in Oklahoma, and is the 120th national cemetery to be administered by the National Cemetery Administration.
