The Great Hall is four stories tall. The walls and columns are made of fossilized limestone, quarried in central Texas. The polished wainscot is made of black marble from the Pyrenees Mountains, which are located primarily in northern Spain. The floor and steps are made of antique Verde marble from Vermont, while the white silvery inlays of the stripes and mosaics are of San Saba stone from central Texas. Lending a touch of warmth and humor to the room are mosaic tile designs of various Texas animals, featuring some of the varied wildlife that greeted the early settlers. The designs include an armadillo, horned frog, rattlesnake, roadrunner, fish, jackrabbit, alligator, eagle, javalina (wild hog), and wild turkey.
