Salmon Falls Mill Historic District

The Salmon Falls Mill Historic District encompasses a historic mill complex on Front Street in Rollinsford, New Hampshire. The complex includes four major structures and seven smaller ones, on about 14 acres (5.7 ha) of land along the Salmon Falls River. They were built between about 1840 and the mid-1860s, and have an unusual architectural unity, for additions made to the buildings were done with attention to matching elements of the existing structures. The Number 2 Mill, built in 1848, was an early location where a turbine was used instead of a waterwheel to provide power to the mill machinery.

The district was listed on the National Register of Historic Places in 1980.
