The Wisconsin State Capitol, located in Madison, Wisconsin, houses both chambers of the Wisconsin legislature along with the Wisconsin Supreme Court and the Office of the Governor. Completed in 1917, the building is the fifth to serve as the Wisconsin capitol since the first territorial legislature convened in 1836 and the third building since Wisconsin was granted statehood in 1848. The Wisconsin State Capitol is the tallest building in Madison, a distinction that has been preserved by legislation that prohibits buildings taller than the columns surrounding the dome. The Capitol is located at the southwestern end of the Madison Isthmus. The streets surrounding the building form the Capitol Square, which is home to many restaurants and shops.
