If your facing the front of the New Orleans Museum of Art (NOMA) in City Park, to your right will be the big lake with the fountain, to your left will be the Sculpture Garden. Walk to your left, just past the entrance to the Sculpture Garden will be the Dueling Oak Tree. It does have a placard as a designation.
This tree is named as the Dueling Oak because of the many arguments solved here with a duel. For some history written by people far more knowledgeable than I am, please look at these articles.

If you even skimmed through these articles, you can see the history of the area and of the tree. Honor and pride are great attributes, but they can also be a downfall. It is a peaceful area to sit and have a picnic, watch the children play, stop a minute and enjoy the shade. Please note that there is no actual restroom here, unless you are into quail hunting, then I would worry about indecent exposure. read more
