“Oklahoma’s Historic Barns”

Presenter: Dr. Brad Bays

Keywords: Barn Types, Upland South Culture, Native American Agriculture, Historic Construction Methods, Barn Survey, NRHP Evaluation, Criteria A and C

Historic barns in Oklahoma are disappearing for a variety of reasons, yet they serve as the most vivid, multigenerational markers of local landscapes, reminding us of the inevitability of economic, technological, environmental, and cultural changes which all places undergo.

Between 2009 and 2014, Brad Bays conducted a survey of the state’s historic barns for the Oklahoma State Historic Preservation Office and the Oklahoma Historical Society. The OK/SHPO’s objective was to document at least 10 historic barns in each county over the span of five years.

Five years later, Brad had logged around 55,000 miles, mostly on county roads, in each of the state’s 77 counties. He had visited more than 5,000 sites and documented just under 1,000 properties for the Oklahoma Landmarks Inventory (OLI), the state’s archive of properties that are National Register-eligible or warrant further study for possible NR listing. Of these, about 100 properties were deemed NR-eligible. The experience had taken him to every corner of every county in the state, and better awakened him to Oklahoma’s substantial diversity. This presentation will provide a geographical overview of the forms and materials of Oklahoma’s surviving historic barns.

The survey discovered rare types of barns not previously known to exist, as well as yet-unclassified types. Log barns of every type can be found throughout the former Indian Territory, and they reflect cultural ties to the Upland South and the effects of prolonged inaccessibility. Native stone and masonry barns are found clustered in pockets around the state, and bank barns tend to be associated with ethnic German settlement. 


Brad Bays is Associate Professor of Geography at Oklahoma State University. He holds a BA from Oklahoma State University (1989), an MS from the University of Tennessee-Knoxville (1991), and a PhD from the University of Nebraska-Lincoln (1996), all in Geography. He has been on the faculty at Oklahoma State University since 1995. His research and teaching interests center on the historical geography and agricultural history of the southern Great Plains, especially his home state of Oklahoma.

NBA Launches Virtual Barn Preservation Lecture Series

Join us for a series of virtual presentations led by experienced practitioners across the country in support of barn-preservation education

All lectures will be hosted via Zoom and are free to attend – open to anyone with an interest in learning more about historic barns!

The first presentation in our series – to be held Wednesday, August 12th at 6 pm EST – is entitled, “How to Speak Barn: the Language and Nuances of Barn Anatomy and the Language We Use to Describe Them.” See the description below for details.

To register for this event, send an email to RSVP with your name and location (city/county, state) to info@barnalliance.org by Sunday, August 9th. We will send an email with the details to call or login to all registrants on August 11th.


August 12th: “How to Speak Barn: the Language and Nuances of Barn Anatomy and the Language We Use to Describe Them”

Presenters: Jeffrey L. Marshall and Michael Cuba

Keywords: Barn Terminology, Barn Types, Outbuilding Identification, Timber-Framing/Historic Construction Methods and Techniques, NRHP-Evaluation, Criterion C

Working in preservation in an agricultural context requires uncommon expertise. Barns and other farm buildings require a specialized vocabulary and a working knowledge of the historical evolution of design and use. Learn the lingo, how to recognize change, and how to evaluate and describe elements necessary for National Register designation.

The language used to characterize our barns has varied from person to person and publication to publication over the centuries. Efforts to develop a coherent and unified way of describing these buildings have come far over the past few decades.

This lecture will explore appropriate terminology and the precedents that support this language. The more familiar we become with common nomenclature, the more effectively we are able to share our observations with one another and the easier it is to evaluate particular barns in context with similar barns.

Although this lecture is geared towards architects, engineers, preservation contractors, cultural resource professionals who may not be familiar with barns and general barn enthusiasts, everyone can learn from this exploration of historic farm buildings!
