Greenwell Springs is an area of Central, Louisiana, United States, a city in the Baton Rouge metropolitan area. It was previously distinct unincorporated community in East Baton Rouge Parish. The ZIP code for this area is 70739.
In the 1850s, Robert W. Greenwell purchased land in the area of what is now known as Greenwell Springs and began developing the area into a rural resort that was built around 10 medicinal springs. Despite the springs being in close proximity to each other, each spring was said to have very different and distinct mineral properties from the others. It was believed that this indicated the springs each came from different levels beneath the ground.
The resort area became known as the Greenwell Springs Hotel, and was used during the Civil War as a headquarters and staging area by Confederate General John Breckinridge. Prior to the Battle of Baton Rouge in April 1862, Breckinridge's forces marched west to attack Union forces that had occupied the city. After the battle, Confederate forces retreated back to the Greenwell Springs Hotel and used it was a hospital for wounded troops. Both Union and Confederate troops were buried on the grounds of the hotel in unmarked graves.
