If you're a book lover there's no better way to celebrate that than by visiting the Boston Public Library, the nation's second largest library. This huge library is home to around 6.1 million books, in addition to about 1.7 million rare books and manuscripts that feature records from colonial Boston, early works of William Shakespeare and the personal book collection of John Adams.
Watch the opening battle of the American Revolution take place right before your eyes at Minute Man National Historical Park. This hallowed ground is where the war began and where it is relived through reenactments. These demonstrations aren't the only things to do at the park though; explore the visitors center, walk down Battle Road Trail, check out the Hartwell Tavern and The Wayside and other park attractions.
Spend some time hanging out in the country's oldest park. The 50-acre Boston Common is the anchor for the Emerald Necklace park system and is the starting place of the famous Freedom Trail. There are quite a few monuments throughout the park, and several outdoor events take place in the Common throughout the year.
