The Museum of the American Revolution celebrates its one-year anniversary this month. Officials say the museum is having success in getting visitors in a city filled with revolutionary war history. You can stop by the Museum of the American Revolution during a visit to Philadelphia, Pennsylvania. Philadelphia was the place where the Declaration of Independence was signed in 1776. A few years later, the city served as the early capital of the United States. The museum will celebrate its first birthday on April 19. That is also the anniversary of the first gunshots fired at the battles of Lexington and Concord, Massachusetts, in 1775. These battles led to the revolutionary war between Britain and its North American colonies.
