The government of Texas operates under the Constitution of Texas and consists of a unitary democratic state government operating under a presidential system that uses the Dillon Rule, as well as governments at the county and municipal levels. Austin is the capital of Texas. The State Capitol resembles the United States Capitol in Washington, D.C., but is faced in Texas pink granite and is topped by a statue of the "Goddess of Liberty" holding aloft a five-point Texas star. The capitol is also notable for purposely being built seven feet taller than the U.S. national capitol.
