The Iowa State Capitol in Des Moines is the seat of the state government and the location of the Iowa Legislature and the governor’s principal offices. The building is noted for its large gilded central dome and four smaller corner domes.

Completed in the late 19th century, the Capitol houses legislative chambers, ceremonial spaces, and offices, and it contains significant interior decoration including murals, stained glass, and carved woodwork. The central rotunda is a major interior focal point and provides an observation area for city views.

The building was constructed over a period in the late 1800s and has been maintained as the core seat of state government since its completion. It remains an active working capitol with regular legislative sessions and public events.

The Capitol sits in downtown Des Moines and is a prominent component of the city’s civic core, within walking distance of other municipal and cultural institutions.

• Gold-covered dome: The capitol’s central dome is covered in gold leaf and the building features four subsidiary domes, creating a distinctive skyline profile.
• Public tours: Free guided tours are offered to the public and commonly include access to the rotunda, legislative chambers, and observation areas during scheduled hours.

What to See#

• Rotunda and observation area: The building’s central rotunda rises beneath the main dome and is richly decorated with murals and statuary; an observation area provides panoramic views of downtown Des Moines.
• House and Senate chambers: The legislative chambers include the House chamber and the Senate chamber, both preserved with period furnishings and decorative artwork tied to the building’s 19th-century completion.

The Capitol is in downtown Des Moines at 1007 E Grand Ave, a short walk from the Pappajohn Sculpture Park and downtown hotels. Des Moines Metro Transit buses serve nearby routes; parking is available at municipal lots.
