Step back in time and explore Leavenworth, the first city of Kansas, built on the edge of a new and exciting western frontier in 1854 when the Kansas Territory opened for settlement. With the arrival of steamboats and railroads, the population of the infant town exploded, becoming a launchpad of western expansion and an innovative, bustling American industry destination on the Missouri River. On loan from the Leavenworth County Historical Society, this exhibit of historical photographs from the post-Civil War era reveals a notable segment of American history in surprising detail and reframes the rich legacy of Leavenworth. The free exhibit is being held at The Box Gallery, 1000 Walnut St., Kansas City, Missouri. The gallery is open Monday through Friday from 8 a.m. to 5 p.m. The exhibit will run through Sept. 8.
