Since its founding in 1651 on the western shore of the Delaware River, New Castle and its residents have shared in the making of American history. Known as the first capital of the first state, this charming town watched European powers clash over its control; welcomed William Penn when he first set foot on American soil; participated in the drama of the Revolutionary War, the War of 1812, and the Civil War; and reaped the benefits of new technologies like the railroad, steam engine, and aviation. Eventually, trade and commerce moved elsewhere, leaving New Castle preserved and intact. Today, the people of New Castle take great pride in their community's heritage and enjoy sharing the story of this National Historic Landmark District with others.
