It is a point of pride for Texans to point out that their capitol building is taller than the nation's in Washington, D.C. Built with limestone from Oak Hill and sunset-red granite from Marble Falls, the Renaissance-revival building has unique features like the rotunda's "whispering gallery" effect. State law protects Capitol-view corridors from 30 vantage points in Austin, ensuring that it has remained a prominent feature of the city.
