The Barker Mill at 143 Mill Street catalyzed the residential development of what became known as New Auburn after Auburn annexed Danville in 1867. The Little Androscoggin Water Power Company was formed in 1870 and purchased a large tract of land there, dammed the Little Androscoggin River in 1872, and completed the five-story mill building with a mansard roof in 1873. The mill was named for the company's directing agent, C.I. Barker. For many years it was Auburn's only textile enterprise, making cotton shirts and sheets. The company laid out 1st through 10th Streets and sold house lots, many to millworkers. In 1874, it also stimulated the building of South Bridge, later renamed Lown Bridge. The mill is now residential housing.
