The Boone County Courthouse is Lebanon's centrepiece, a handsome limestone building in the Beaux-Arts style occupying the town square. The interior features a stained-glass dome and a three-storey rotunda that gives the building a sense of grandeur unusual for a county seat of this size. The courthouse is still fully operational as a working government building.
Around the courthouse square, the streets have the pleasant, slightly frozen-in-time feel of small-town Indiana. Several of the original commercial buildings from the early twentieth century still stand. It makes for an agreeable short walk, and the scale of everything — nothing is very far from anything else — suits an afternoon of easy exploration.
