Old Cowtown Museum's collections reflect aspects of life on the frontier in the late 1860s and 1870s. They include historic structures and their period furnishings, clothing and domestic textiles, tools and machinery, farming equipment and rolling stock. An archival collection of photographs, letters, and documents also provide primary source material for historical research. A separate study collection and reproductions are used by costumed history interpreters to bring this historical period to life.
T​here are 54 historic and recreated buildings at Cowtown located along the banks of the Arkansas River that are open to visitors all year long. Twenty-seven of the buildings are original and have been relocated to the grounds from Wichita and other sites in Kansas. Relocation of these structures protected them from demolition and preserved them for the future.
