Built in 1907 in Erick, Oklahoma, the First National Bank stood for decades at the center of the town’s business life and remained in operation until 1968. Though chiefly a bank, the two-frame building also housed barbershops, professional offices, and the courts of local justices of the peace, making it a broader civic and commercial hub during Erick’s early history. After the bank closed, it became the 100th Meridian Museum. Its significance also includes a benchmark set into its wall from the survey of the 100th meridian west, a link recognized when it was listed on the National Register of Historic Places in 1979.
