Welcome to the Mystic River Historical Society.

MRHS is located in Mystic, Connecticut, centered around the famous Mystic Bridge which has connected the towns of Groton and Stonington for nearly 200 years. We are some 300 strong and have been dedicated to preserving and promoting the history of the greater Mystic area since 1973. We’re a totally volunteer organization offering a wide variety of opportunities for those who are willing and able to contribute time and energy.

On October 25, 2023, the Mystic River Historical Society received an official citation from the Connecticut General Assembly in recognition of  its 50th anniversary (above right).  The citation was introduced by Senator Heather Somers and Representatives Gregory Howard, Aundre Bumgardner, and Christine Conley.

The Connecticut League of History Organizations (CLHO) awarded MRHS a 2023 Award of  Merit for the Mystic River Bascule Bridge Centennial project.  MRHS board members Elizabeth Boucher and Marilyn Comrie created the Mystic River Bridge display  at the Groton Public Library and authored the bridge souvenir booklet and hard cover book Walk Your Horses. Board member Jim Streeter gave a talk on the history of the Mystic River bridges.  MRHS also served on the Chamber of Commerce’s bridge anniversary committee to help with the many bridge-related activities held during last year’s bridge centennial, and worked with Firesite Films on their production of numerous short videos related to the bridge and its history.

Elizabeth Boucher and Marilyn Comrie accepted the Award of Merit on April 18, 2023 at Central Connecticut State University.  In addition to the Award of Merit, MRHS received an official citation from our local state representatives and senator acknowledging MRHS’ work on the bridge centennial.

On May 1, 2023, the Mystic River Bridge centennial plaque was formally unveiled.  The plaque is mounted on the bridge tender’s house.  MRHS is proud to have significantly contributed to the many activities that celebrated our 100 year-old bridge and is grateful for the recognition by the Greater Mystic Chamber of Commerce.
