Spann House and National Foundation Life Center Added to National Register of Historic Places
OKLAHOMA CITY — The Oklahoma Historical Society and State Historic Preservation Office (SHPO) are pleased to announce the National Register of Historic Places designation for the following properties in Oklahoma. The National Register of Historic Places is our nation’s official list of properties significant in our past.
Cleveland County
Spann House
6810 E. Lindsey St., Norman, Cleveland County
Located between the city of Norman and Lake Thunderbird in Cleveland County, the Spann House, also known as Acorn Hill, is listed in the National Register of Historic Places for its Mid-Century Modern architectural style, which borrows from the icons of the day, such as Bruce Goff and Frank Lloyd Wright. Built between 1959 and 1960, and designed by Goff student Robert L. Thomas, the Spann House is an excellent local example of modern American architecture that has withstood the test of time while holding its historical integrity.
Oklahoma County
National Foundation Life Center
3535-3555 NW 58th St., Oklahoma City, Oklahoma County
Oklahoma City’s National Foundation Life Center, known today as the Landmark Towers, is located along Lake Hefner Parkway and Northwest Expressway. Built between 1967 and 1971, and designed by architectural firm Alan Lower & Associates, the National Foundation Life Center is listed in the National Register of Historic Places for its significance in community planning and development as part of the post-World War II suburban commercial development trend and its architectural significance as an excellent example of the New Formalist subtype of the Modern Movement.
Listing in the National Register of Historic Places is an honorific designation that provides recognition, limited protection and, in some cases, financial incentives for these important properties. The SHPO identifies, evaluates and nominates properties for this special designation.
The State Historic Preservation Office is a division of the Oklahoma Historical Society.
