Ganongadan State Historic Site, at the location of the largest Seneca village of the 17th century, is the only State Historic Site dedicated to the interpretation of Native American history. The Seneca Art & Culture Center offers multimedia-rich interactive exhibits on the Haudenosaunee (Iroquois) contributions to American culture, government, foodways, and art. The full-size bark longhouse showcases the daily life of a 17th-century Seneca family. Both structures sit within the 569-acre grounds, which include three walking trails with interpretive signs and feature traditional Seneca and Haudenosaunee plants.
