History of Moon, South Carolina

Moon, South Carolina, is a rural crossroads community located in the heart of Chester County.

The name “Moon” is believed to have come from a local resident, William Moon, who donated land for a Methodist church.

In the early 1900s, Moon experienced a period of agricultural prosperity, with cotton being the primary crop. However, like many rural communities, it faced economic challenges during the Great Depression. The decline of cotton farming and the mechanization of agriculture led to a decline in population and economic activity.
