After Garza County's creation in 1876, it was not formally organized until 1907, at the initiative of cereal producer C. W. Post. In 1922, when the population had grown to about 4500 and the cotton industry had spurred economic growth, citizens approved the sale of bonds to finance a new courthouse. The commissioners court selected prominent regional architect Guy Carlander of Amarillo to design the courthouse and awarded the construction bid to the Fred T. Bone Company, also of Amarillo. Built in 1923 of reinforced concrete with a brick exterior and cast stone details, the Garza County courthouse is a late but fine example of Prairie School architecture.
