Over 375 years old the Sallier Oak towers over the grounds of the Museum. It was here on the site of the Museum that Charles Sallier, whom the lake and city takes its name, built his winter home under the shade of this very oak tree.

The tree is a live oak and is on the registry of the Live Oak Society of Louisiana. The tree has survived many storms and hurricanes, and if one looks close enough you can see the remnants of chains hanging out of the trunk.

The chains were used to heal the tree after lightning struck and split one of its largest branches. Unfortunately the limb was taken over to rot and had to be removed. The tree has since grown around the chains and has continued to grow exponentially over the years.
