I tend to think of a city as a boring grid of streets. It turns out that the people who planned about 85% of the county seats in Indiana felt the same way since they feature what historians call a Shelbyville Square, a regular old city block bounded on each side by a street. Ironically, Shelbyville, Indiana lacks a Shelbyville Square. You’ve got to travel four blocks south of the city’s Lancaster Square to see the courthouse, but once you do, you’re in for a treat: Shelby County’s is one of only three art deco examples in the state.
