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
