Founded in 1812, Evansville is the third-largest city in Indiana, located on the Ohio River in the southwestern corner of the state. The city grew out of the bustling river trade that developed during the steamboat era of the 1800s. Evansville's importance as a river port expanded with the completion of the Wabash & Erie Canal that connected the Great Lakes to the Ohio River. The downtown area boasts a number of historic buildings as well as a historic district that features the city's grandest Victorian-era homes. The seat of Vanderburgh County, the city serves a large trade area in Indiana, Kentucky, and Illinois. It is home to the headquarters of Berry Plastics, Old National Bank, and Vectren.
