Walnut Park Farm Historic District, Historic farm district near St. Joseph, Missouri.

Walnut Park Farm Historic District, also known as the R.L. McDonald Farm, is a livestock breeding farm near St. Joseph, Missouri. It holds four contributing buildings, one contributing site and one contributing structure, including a 1+1⁄2-story gabled ell brick residence (c. 1880, since demolished), an L-form basement barn (c. 1870), a stable (c. 1890) and a root cellar (c. 1900).

The property evolved from a modest farm into a major livestock breeding operation between 1870 and 1914. During this span, most buildings were constructed according to the modern agricultural standards of the era, reflecting the growing demands of an expanding farming enterprise.

The farm carried several names over time: R.L. McDonald Farm, Country Club Farm, Creek Farm and Schreiber Farm. Its purebred horses were trained and shown to buyers in an enclosed track and show ring, a practice tied to the farm's livestock breeding business.

The district lies near St. Joseph in Andrew County, Missouri, and is a listed historic site rather than a staffed attraction. The brick residence was demolished, so the remaining barn, stable, root cellar and track site are what can be seen. Check the National Register listing for the address before visiting.

The property contains remnants of an enclosed track and show ring where purebred horses were trained and displayed to prospective buyers. This infrastructure reveals that the operation served as a sales center for high-quality breeding stock, not just as a production farm.
