Wisconsin State Capitol
The Roman Renaissance–style Wisconsin State Capitol is the only state capitol building along an isthmus. Although the fifth building to serve its function, the capitol now holds the title as Madison's tallest building (only three feet shorter than the capitol building in Washington, D.C.) and attracts throngs of architecture and design enthusiasts. Its granite dome (the world's largest) rises above downtown Madison's skyline on Capitol Square. Rooms feature Italian marble, Wisconsin-oak furniture, murals, and paintings. There are free 45-minute guided tours multiple times daily.
