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 historical traditions 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.

Hours and Directions

The Mystic River Historical Society is excited to be partnering with the Greater Mystic Chamber of Commerce this year to mark the 100th anniversary of the Mystic drawbridge. There is a lot going on and we invite our members and the public to join in all the activities for this special milestone.  See below for activities with major MRHS involvement.  For information on the many other celebration activities, click here. You can also download the GO MYSTIC app. The bridge centennial celebration is scheduled for Saturday, Oct. 15 with daylong activities, a special program in the afternoon featuring local community leaders, and fireworks on the Mystic River around 7:30 p.m. to cap off the evening. We invite everyone to come downtown and party!


Historical Society members Elizabeth Boucher and Marilyn Comrie have also assembled a 56-page souvenir booklet titled “Centennial Celebration of the Mystic Bascule Bridge” to commemorate the bridge’s 100th birthday. It contains 13 stories about the history of the bridge and nearly 75 photos from the society’s archives. It is for sale for $12 at the bridge centennial’s visitors center in the former Mystical Toys building next to the drawbridge. Fifty percent of the proceeds from the sale of the book will benefit the historical society.


The headquarters for the bridge centennial celebration is in the visitors center in the former Mystical Toys building by the bridge. Hours of operation are 11 a.m. to 5 p.m. daily. In addition to a variety of items for sale to commemorate the 100th anniversary of the bridge, there is a large collage covering one wall of the center featuring 12 photos of the bridge from the historical society’s collection. After you view the collage, take time to write your thoughts about the bridge in a special logbook.


Historical Society members Elizabeth Boucher and Marilyn Comrie are working on a 104-page coffee table book commemorating the bridge centennial. It will feature 25 stories about the bridge, including a timeline showing how the bridges in Mystic have evolved to meet the needs of the village. There will be a section of the book highlighting in photos all the activities this year to mark the bridge’s 100th birthday. The book will be available in December, just in time for holiday gift giving. There will be a form available soon to pre-order the book. Fifty percent of the proceeds will benefit the historical society.
