Swing by La Rochelle during the Bar Harbor Historical Society’s free community day! Admission to the museum will be free 10-3 as you enjoy live music, fun & games, food and sweets. We will be there sharing our new digital tour with people and helping them download the app and navigate the 21 stops. Everyone who downloads the MDI History Adventure App with us will get an entry into our What Happened Here? contest. Winners will be announced on October 27.
