Powered by the West River

South Londonderry Village Historic District, located in south-central Londonderry and built along both sides of the West River, flourished in the early 19th century, taking advantage of the drop in the river's elevation to power early industrial works. Three dams were built at various points across the river: the largest one right upstream from the bridge. Most of the houses are wooden frames, standing 1-1/2 to 2-1/2 stories high, with modest decorative elements in traditional 19th-century architectural styles.

The village boasts two 19th-century church buildings, two former school buildings, and the 1860 Londonderry Town House, where municipal offices, auditorium, and meeting spaces reside. Residential construction was hemmed in by the steep hillsides, resulting in a linear layout along the river. Listed on the National Register of Historic Places in 1986, the village retains its well-preserved mid-19th-century core. In the early 19th century, many industrial sites were built, although most are now little more than foundations. Three dams were built across the river at various points.
