Springfield Armory National Historic Site | Springfield, Mass.
The Springfield Armory in Massachusetts is a great day trip for history lovers in Boston, Hartford or Albany. Created in 1777, the armory served as the Continental Army’s first and main arsenal, responsible for manufacturing and storing ammunition and weapons, until it was closed in 1968.
In the 1970s, the site became a National Historic Site run by the National Parks Service. Today, visitors can explore the grounds, tour the historic arms collection and participate in interpretive guided tours for free.
