The lime industry used to be the chief industry of Erin, TN and in 1871 this pair of limekilns was built. The twin kilns are about 25 feet tall and 19 feet square at the base. They are located on the west side of town along Main St. (which is also state highway 49). There are four Limekiln sites in the county. Based on their importance to the history of the county, this pair as well as the one at the quarry a few blocks away are listed on the National Register of Historic Places.
