The Hanover County Courthouse is an operating courthouse. Located along U.S. Route 301, it is across the green from the Hanover Tavern. The courthouse is the third oldest courthouse still in use in the United States. Some local historians cited the courthouse as built in 1735, but the state historical society notes it was built between 1737 and 1742.[4]
