The state capitol grounds are famous for active oil wells located there and remains the only state capitol with oil rigs on the property. They are easily visible from the street. Oklahoma City sits directly on top of the Oklahoma City Oil Field.
The state capitol was originally announced by the capitol commission to be built far from downtown at NW 42nd and Ann Arbor. The proposal, by Israel Putnam, was approved and plans were laid for the capitol to front NW 39th Street. Later, the commission was deemed to be illegal and a new commission accepted a proposal from E.K. Gaylord and others for the present site of the capitol grounds.
