The big limestone Beaux-Arts courthouse that anchors the south end of downtown was completed in 1921, replacing earlier county courthouses on the same site. Topped with a copper dome and faced with locally quarried Kansas limestone, it is the kind of small-town civic building that the Federal Writers' Project used to celebrate — solid, slightly grandiose, and intended to last.
You can walk into the rotunda during business hours; the interior is more modest than the exterior suggests. From the courthouse, the downtown historic district stretches a couple of blocks north along Buckeye Avenue with banks, the old post office, and various late-Victorian brick storefronts. Free; combine with a walk through the historic district.
