The Nicholas Jarrot Mansion, built between 1807 and 1810 gives evidence of the western transmission and construction of an early American architecture: the Federal style. Located at the western boundary of the Northwest Territory, within the French Colonial region of the Mid-Mississippi River valley, the design and contruction of the Jarrot Mansion is an early and rare example of the Federal style in a region that was detached as a territorial wilderness. It is a solid masonry building constructed within the early development of the Northwest Territory as an expression of the architectural evolution within the early western expansion of the American territories. The mansion signifies an individual intent to reach beyond the local building traditions and customs of the provincial region of the mid-Mississippi River valley toward a broader architectural genre. -- National Historic Landmark statement of significance, August 7, 2001
