Welcome to the Mystic River Historical Society.

MRHS 50th Anniversary Gala
The Mystic River Historical Society celebrated its 50th Anniversary on September 24th – the exact date on which MRHS held its first meeting – with a gala at the Mystic River Yachting Club at the Mystic Shipyard on Willow Point in West Mystic. Attended by 125 people, there was all the great music of the 1970s, dancing, and a bountiful buffet provided by Lancer Caterers. Charter Members, i.e., those who were members during MRHS’ first year (1973-1974), were special guests. A slide show depicting MRHS’ 50-year history in photographs was shown throughout the evening and is viewable here. See Scenes of Mystic for photographs of the gala. Many thanks to board members Grace Cleere and Nancy Potter for organizing this successful event!

The Connecticut League of History Organizations (CLHO) has 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 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.

As the culmination to this past year’s celebration of the 100th anniversary of the Mystic drawbridge, the Greater Mystic Chamber of Commerce published a hard cover book, “Walk Your Horses, The Story of the Mystic River Bridge,” authored by MRHS board members Elizabeth Boucher and Marilyn Comrie. The book can be purchased at the Chamber’s Visitors Center on the east (Stonington) side of the bridge. The book can also be ordered online through the Mystic Chamber of Commerce website. Note that the 56-page souvenir booklet, “Centennial Celebration of the Mystic Bascule Bridge,” is available for purchase, too. Both can be purchased from MRHS.
