Treaty Oak is by far the most famous tree in Austin. This 500 year old giant was once one of fourteen trees referred to by local Indians as the Council Oaks. Treaty Oak in particular was revered by both the Commaches and Tonkowas. Legend states that it was under this tree that Stephen F. Austin signed a treaty with the Indians from which its name was derived. This majestic tree once sported a 127 foot spread and was considered to be the finest example of a mature oak in the world. In 1929 the tree was added to the American Forestry Association's compilation of famous and historic U.S. trees.
