Unusual "squirrel cage" jail, listed on the National Register of Historic Places, also serves as a visitors' information center in Gallatin, MO.
The Daviess County Squirrel Cage Jail was completed in 1889. Its unique architectural design provided answers to concerns about prisoner security, worries about both prisoners breaking out and accomplices breaking in: rotary jails, where a round "squirrel cage" divides into jail cells and spins on a single axis inside a perimeter of stationary bars.
Eight rotary jails are known to have been constructed, all variations of the patented design by the Pauley Jail Building & Mfg. Company of St. Louis. Only three still stand today as visual markers of yesteryear.
