The Texas Capitol is usually regarded as one of the most distinctive state capitols in the country. In 1970, it was included to the National Register of Historic Places, and in 1986, it was named a National Historic Landmark. Tours are free and guided. Monday-Friday, 8:30-4:30 p.m.; Saturday, 9:30-3:30 p.m.; and Sunday, noon-3:30 p.m. Closed major holidays. The Texas State Capitol is both a legislative building for the Texas Legislature and the official residence of the governor. It is located at 1001 Washington Avenue in Austin, Texas 78701. The grounds include gardens, monuments, and other features that were originally part of an estate called "La Grange." La Grange was donated to the state by Edward Clark, a wealthy former slave owner from Mississippi. The land was set aside as a public park but was later used as a burial ground for many of Austin's early settlers. In 1874, the state legislature authorized the construction of a new capitol building, and the foundation was laid the following year. The current structure was completed in 1889 after several changes had been made to its design. It was modeled after the United States Capitol in Washington, D.C. The interior has been updated several times over the years but remains largely unchanged since then. Guided tours are available daily except for some federal holidays. Visitors can view two rooms on the first floor that contain photographs and documents related to the history of the Texas State Capitol.
