My answer to this question is that the north and south battery are shoreline batteries, small ports used for defense that is found in the Boston harbor.  Boston was known for its trading industry and these might be their line of defense to protect this City. 

Between the north and south battery on Boston harbor people could visit the Boston Children’s Museum, right on Children's Wharf, along the Fort Point Channel, with many amusing activities for young children's education; or Massachusetts Bay Lines over 60 Rowes Wharf, with its popular "Thirsty Thursdays", a place to get cold craft beers with friends.

Additionally, people could also visit Quincy Market, one of the largest market complexes in U.S.A., and The New England Aquarium with entertaining live animal displays all the time.
