It is a grist mill located astride Briggs Brook between bridges carrying the eastbound and westbound lanes of Interstate 95.

Some elements of the mill infrastructure may be very nearly original to the period of first use, notably the elevated flume, wheel pit, and tail race.

The present building may also include elements of the original, although it is known that the mill was set afire during Benedict Arnold's 1781 raid on New London and Groton.

[2] The Mill was used as the primary filming location for the 1920 Vitagraph movie of the O. Henry short story The Church With an Overshot Wheel.
