Spray Industrial Historic District, Industrial historic district in Eden, North Carolina, US.

The Spray Industrial Historic District is an industrial section of Eden, Rockingham County, North Carolina, with 70 contributing buildings, 9 contributing structures and 1 contributing object. It covers eight textile mill complexes, mill village housing and seven commercial buildings, among them the Morehead Cotton Mill complex, the Nantucket Mills complex designed by R. C. Biberstein, the Smith River Dam and Spray Power canal, and the Imperial Bank and Trust Company of 1912.

The district emerged as a center of textile manufacturing and was shaped by the founding of several major mills that drove economic growth in Rockingham County. During World War I, factories including the Carolina Cotton and Woolen Mills produced blankets and other materials for military use.

The district reflects a community built around textile mills, where workers and their families organized daily life around factory operations. Today visitors can still see how closely residential areas were linked to the production sites.

The district can be explored on foot since the buildings and structures are spread throughout a cohesive area. It helps to start with an overview to understand the different mills and their locations along the Smith River.

The Smith River Dam and Spray Power Canal were engineering structures specifically designed to power multiple mill operations, showing how water energy shaped industrial development. This infrastructure remains today and tells the story of dependence on waterpower in that era.
