The Concord Museum, at 53 Cambridge Turnpike, has a collection of artifacts used on the day the American Revolution began: Muskets, powder horns, flints, and of course, one of the two lanterns that Paul Revere had placed in the steeple of Boston’s Old North Church to signal the patriots of the advance of the Redcoats. (Other periods of Concord history are represented, too, including Henry David Thoreau’s desk and other items, and Native American stone tools going back 10,000 years.) Watch the Museum’s website for an all-new exhibit opening in 2021 that tells the story of April 19, 1775.
