First Regiment Infantry Museum
The 1st Regiment Infantry, Pennsylvania, or "The Dandy First," is recognized by the United States Army as the oldest continuously existing command in the Pennsylvania National Guard, and the only existing Pennsylvania unit with service in the Continental Army, representing Pennsylvania. Now designated the 103rd Engineer Battalion Pennsylvania Army National Guard, the unit has fought in nearly every major American war, initially being involved in the French and Indian War and then the Revolutionary War. The 103rd Engineer Battalion Armory today houses the 1st Regiment Infantry Museum dedicated to the history of this storied command. Its archival collections are comprised of over 100 linear feet of materials dating from 1812, including regiment minute books, roll books, officers' letter books, account books, and photograph albums.
