Smith Field, historically known as the Paul Baer Municipal Airport, is a highly significant landmark in Fort Wayne, Indiana, representing the pioneering era of commercial and municipal aviation in the United States. Established in 1919, it stands as one of the oldest continuously operating airports in the state and served as Fort Wayne's primary municipal airport during the Golden Age of Aviation. Originally named in honor of Paul Baer, a Fort Wayne native and America's first World War I flying ace, the airfield was renamed Smith Field in 1947 to honor Arthur "Art" Smith, another legendary local aviator and pioneer airmail pilot. The field played a vital role in the early development of the nation's airmail service, serving as a critical stop on transcontinental routes and fostering the growth of civil aviation in the Midwest.

The historic district encompasses a remarkably preserved collection of aviation infrastructure that reflects the architectural and functional trends of early 20th-century airports. Prominent among these is the main hangar and administration building, constructed in approximately 1930, which exhibits a distinctive blend of utilitarian design with Tudor Revival and Art Deco architectural details. Along with its historic beacon tower, the site retains a high degree of physical integrity, capturing the spirit and technology of the pre-World War II aviation boom. Listed on the National Register of Historic Places in 2002, Smith Field remains an active general aviation airport and a living monument to Fort Wayne's rich aerial heritage.

The Chief Jean-Baptiste de Richardville House, located in Fort Wayne, Indiana, is of exceptional historical significance as the home of the principal chief of the Miami Nation from 1812 until his death in 1841. Constructed in 1827, the two-story brick residence was partially funded by the United States government under the terms of the 1826 Treaty of Mississinewas, reflecting the unique geopolitical influence of Chief Richardville (Piniwa). As a highly shrewd diplomat, trader, and leader, Richardville amassed a vast fortune through his control of the strategic portage between the Maumee and Wabash rivers, making him one of the wealthiest men in the state of Indiana at the time. The house serves as a powerful testament to the complex treaty-making era, during which the Miami Nation negotiated to maintain their sovereignty amidst intense pressures of American westward expansion.

Architecturally, the Richardville House is distinguished as the oldest surviving Native American residence in the Midwest and is believed to be the first Greek Revival-style home built in Indiana. The grand, Euro-American style of the home was a deliberate projection of Richardville's high social and economic status, demonstrating his ability to navigate white society while remaining a fierce protector of Miami land and culture. Because of its profound association with Native American leadership, trade, and cultural adaptation during the removal era, the property was listed on the National Register of Historic Places in 1997 and was subsequently designated a National Historic Landmark in 2012.
