The Old Courthouse is located in the small town of Mount Gambier., (Limestone Coast), on the limestone coast of South Australia.
The Old Courthouse, which became operational in 1865, was a local law enforcement center, where a number of important criminal cases were adjudicated until the completion of the new court in 1975.
Today's The Old Courthouse still retains the court furniture of the time and is open to the public as a historical heritage of Mount Gambier. The venue can serve wedding, meetings and mock trials. It is suitable for school groups and various adult groups to watch. It also encourages tourists to actively participate in activities and have a pleasant and interesting experience.
