The central room of this T-shaped building is the Great Hall.  On the far end of the Great Hall is a gold medallion, twelve feet in diameter.  The five-pointed star, the symbol of Texas, is surrounded by six female figures, each representing the history of Texas under the flag of six nations.  These nations are: the Union, the Republic of Texas, the Confederacy, Mexico, France, and Spain.

The two three-story high murals were painted by Eugene Savage and depict Texas history from the 1500s through 1936.

The mural on the north wall represents principal events in the history of Texas from European arrival to the founding of the Republic of Texas.

The ceiling features hand-stenciled designs of stylized animals representing the Southwest: a roadrunner with a snake in its bill, and an armadillo.  The other two designs are abstractions representing the land and the sea.  The columns of fossilized shellstone support the ceiling from which the ten chandeliers hang.  Mosaic tile designs of various Texas animals (including an armadillo, a horned frog, a rattlesnake, a fish, a jackrabbit, an alligator, an eagle, a javalina, and a wild turkey) are inlaid on the marble floor.

The second mural covers Texas' settlement and economic developments.

In both murals, large beams of silvery light symbolically divide separate changes of time and separate the various periods of Texas history .

This section of the mural depicts Travis standing with sword in hand. Bowie, ill, is being carried over the line, while Crockett and the others follow.  Next to Travis, men at Gonzales, Texas, protect their cannon, daring the Mexican Army to "Come and Take It."
