Located on the eastern bank of the Mississippi River, the Baton Rouge area owes its historical importance to its strategic site upon the Istrouma Bluff, the first natural bluff upriver from the Mississippi River Delta at the Gulf of Mexico. This allowed the development of a business quarter safe from seasonal flooding. In addition, it built a levee system stretching from the bluff southward to protect the riverfront and low-lying agricultural areas.
