This article explores New Hall’s significant role in U.S. military formation, key exhibits, visitor tips, and connections to Philadelphia’s broader cultural and museum scene, offering tourists a rich and engaging itinerary.

 

The Origins and Historical Importance of New Hall

Built by the Carpenters’ Company of Philadelphia in 1791, New Hall was originally the guild’s own meeting place. However, when the War Department required more permanent office space after the formation of the United States Army, New Hall became the government’s military headquarters. Henry Knox, the first U.S. Secretary of War and a trusted aide to George Washington during the Revolution, operated out of this building, overseeing the fledgling nation’s defense at a time of political uncertainty and external threats.

Though the original building was demolished in the late 1950s, a meticulous reconstruction was completed in 1960 on the original foundation, preserving its Georgian architectural style and layout. It housed some of the earliest offices and administrative functions shaping the country’s military and defense policies.

 

Exhibits and Displays: Birthplace of the Pentagon

New Hall’s compact museum space offers captivating exhibits focused on the origins and evolution of the U.S. Army, Marine Corps, and Navy. It proudly holds the nickname “Granddaddy of the Pentagon” for its critical role as the first War Department headquarters in America.

• Historic weaponry such as muskets, blunderbusses, and grenades used by Marines during the Revolutionary War.
