Also known as the Ernest Whitworth Marland Mansion or the E.W. Marland Mansion, the Marland Estate is a Mediterranean Revival style historic house that was once owned by Oklahoma?s former governor and oilman, E.W. Marland. It was built in 1925 with 55 rooms, after the design of John Duncan Forsyth.

The Marland Estate is now a tourist and educational attraction that is open to the public. It features a series of smaller museum, including the Bryant Baker Gallery, the John Duncan Forsyth Room, the Marland Family Exhibit, and the Marland Oil Museum.

Added to the National Register of Historic Places in 1973, the Marland Estate is now being run and managed by the Marland Estate Foundation. It is open for tours daily.
