A.R. Bowman Memorial Museum is on US 26 at the corner of 3rd and Main sts. Housed in a 1910 stone building constructed of locally quarried rocks and initially occupied by the Crook County Bank, the museum offers artifacts and memorabilia from the 1870s through the mid-20th century. Among the displays are exhibits depicting the pioneer life of the county's settlers and such items as firearms, logging instruments, railroad equipment and cowboy regalia.
Following a recent expansion, the museum now includes a second building containing three new exhibits, including one about businessman Les Schwab, who started his tire company in Prineville. The other exhibits explore the local forest and timber industry, and ranching and farming life. Much of the bank's original interior, including its marble counters, bronze teller cages, alabaster chandeliers and walk-in vault, remains intact.
