History

Hillsboro was originally called Monticello, and under the latter name was platted in 1839, and named after Monticello, home of President Thomas Jefferson. The name Monticello was afterwards changed because the U.S. postal authorities refused to accept that name, there being another post office in the state with a similar name. The present name Hillsboro is the English equivalent of the Italian name Monticello. A post office has been in operation at Hillsboro since 1838.

The Thomas C. Fletcher House and Sandy Creek Covered Bridge are listed on the National Register of Historic Places.
