Happy ! Jefferson County, FL is the only county in the state that extends from Georgia to the Gulf of Mexico. It was named for the third president, Thomas Jefferson.
The county seat is Monticello, which was named for Jefferson's Virginia home. The county courthouse was constructed in 1909 in the classical revival style and sits at the intersection of US 90 and US 19. Edward Columbus Hosford was the architect who designed it. He also designed six other county courthouses in Florida.
