Replica of Monticello
Paducah, Kentucky
It can't be cheap to build a replica of Monticello, the famous plantation home of President Thomas Jefferson. This one serves as the office of a spinal surgeon; others double as banks or well-to-do private estates. It's known that Jefferson hurt his back while working at Monticello, so the spine doctor connection makes sense.
But why in Paducah? Jefferson did have a couple of tenuous connections to the city. He authorized the Lewis & Clark expedition, which stopped only a mile or so away down by the river (There's a statue commemorating it there). Also, Jefferson's kid sister, Lucy Jefferson Lewis, is buried a couple of miles east of town along Hwy 60. But if you built a replica of Rocky Hill, her plantation home, no one would stop and take a picture.
