The first courthouse for the county was built in 1755 in the Morristown Green. The second one was built in 1770, also in the Green. In 1826, the county decided to build a third courthouse, located on Washington Street. It was designed by architect Lewis Carter featuring both Greek Revival and Federal architecture. The three-story building was completed in 1827 by contractor Joseph M. Lindsley using brick with brownstone trim.[4]
