Our county is steeped in hundreds of years of rich history in coal mining, therapeutic mineral springs, Native American culture, agriculture, and friendly people.
The area got its nickname ‘Little Egypt’ due to its proximity to the Mississippi and Ohio rivers and the landscape’s similarity to the areas along the Nile River in Egypt. Our history is well-preserved in the museums and historical monuments and sites that can be found scattered throughout our friendly towns and communities. In addition, the Williamson County Historical Society offers tours of the Williamson County Historical Museum in Marion and the opportunity to study history in its research library.
