Beacon Falls is almost 10 square miles and is located along the Naugatuck River in southwest Connecticut. Parts of Beacon Falls came from the neighboring towns of Naugatuck, Bethany, Seymour and Oxford. The first friction matches were made by Thomas Sanford in 1834 in Beacon Falls.

Surrounding Beacon Falls is a landscape of beautiful hills rising from the banks of the Naugatuck River. The town is easy to get to from route 8 and residents have only a short drive to the theater, playhouses, museums, and nature centers in nearby communities. For commuters, New Haven and the larger cities are easily accessible by train.

There are a wide assortment of housing options available including traditional single-family homes, brand new subdivisions, some apartments and delightful condominiums in a converted downtown mill.
