The Treaty Oak, a Southern live oak in Austin, Texas, is the last surviving member of the Council Oaks, a grove of 14 trees that served as a sacred meeting place for Comanche and Tonkawa Tribes. Foresters estimate the Treaty Oak to be about 500 years old and, before its vandalism in 1989, the tree's branches had a spread of 127 feet. The tree is located in Treaty Oak Park, on Baylor Street between 5th and 6th Streets, in the West Line Historic District.
