In short: Completed in 1917, the Wisconsin State Capitol is a masterpiece of architectural endurance. It replaced a predecessor destroyed by fire and was designed to ensure no side of the building felt like the back. Today, it stands as a National Historic Landmark, protected by laws preserving its iconic skyline prominence.

The current Wisconsin State Capitol, the fifth to serve the state, was completed in 1917 after a devastating 1904 fire gutted its predecessor. Architect George B. Post & Sons designed the structure in an X-shaped pattern with four wings, ensuring the building appeared identical from every angle to satisfy businesses on the surrounding Capitol Square. The construction was a massive undertaking, utilizing 43 types of stone sourced from six countries and eight states. Its exterior is composed of Bethel white granite from Vermont, creating what is recognized as the largest granite dome in the world.

The building's interior is equally ornate, featuring marble from France, Italy, Greece, Algeria, and Germany, alongside American stone from states like Tennessee and Wisconsin. The dome is topped by a three-ton bronze statue known as the Wisconsin, or the Golden Lady, sculpted by Daniel Chester French. Standing 15 feet, 5 inches tall, the figure wears a helmet adorned with a badger, the state animal, and holds a globe with an eagle. The ceiling inside the rotunda displays a complex mural titled Resources of Wisconsin, which was painted in segments and assembled like a puzzle due to the dome's curvature.

The Capitol's history is marked by both tragedy and evolution. During an 1883 expansion, a wing collapse killed five workers, an event that haunted witness Frank Lloyd Wright. Later, the 1904 fire destroyed priceless records and the taxidermied remains of Old Abe, a Civil War mascot eagle that had lived in the basement. Following a comprehensive $158.8 million restoration between 1988 and 2002, the building was modernized with updated mechanical systems and restored to its original 1917 aesthetic. Today, it remains the tallest building in Madison, a status protected by state law to prevent surrounding construction from obscuring its dome.
