The first courthouse in Greene County was a frame building built in 1856 for $1,825. Prior to that time the county officers were housed in the Thomas Phillips Building. The second courthouse was completed in 1870 for $37,000. The building featured a bell in the cupola that served as a fire alarm, called the court into session and announced curfew. The present courthouse was dedicated in 1917 and was built at a cost of $200,000. A monument to President Abraham Lincoln was added in 1918 to commemorate the Lincoln Highway, which passes in front of the courthouse. The Mahanay Tower was built on the southwest corner of the courthouse grounds in 1966. In 1993, the Lindsey Memorial, commemorating Greene County native Darrell R. Lindsey, posthumous World War II Medal of Honor recipient, was relocated from the Lindsey Air Station in Wiesbaden, Germany to the southeast corner of the courthouse grounds.
