MICHIGAN CAPITOL VIRTUAL DOME TOUR

Explore the Dome - from Home!

The dome of the Michigan State Capitol, constructed from 1877 to 1878, stands as one of the first state capitol domes built of cast iron - second only to the Alabama and California state capitols.

Designed in the decade following the Civil War, the dome emerged as a proud symbol of freedom and liberty for all. At a time when the nation was healing from immense sacrifice, it became a beacon, inspiring more than 35 states to construct domed capitols that followed the architectural precedent that Michigan helped set.

Soaring 267 feet into the air, the dome was accessible to the public until the early 1950s. After a 1951 fire destroyed the top two floors of the nearby State Office Building (today the Elliott-Larsen Building), the Capitol dome was closed to the public by order of the fire marshal.

For the first time since its closure, we are giving the public the opportunity to climb the height of the dome - from wherever you happen to be! Join us on this virtual tour and ascend beyond the stars to experience the true height of the Michigan State Capitol.

Rotunda Oculus

The term “oculus” means “eye” in latin and is classically used as an architectural term for a round opening or window. The most well known architectural oculus, and likely the strongest influence for our Capitol’s oculus, is the Pantheon in Rome. But while the oculus at the top of the Pantheon’s dome is an open hole to the sky above, our dome only mimics the sky above with beautiful gold and silver stars!

Inside the Dome - Oculus Level - North Side

Welcome “inside” the dome! Whereas the stars are designed to feel like the top of the building, you’ll find that the true height of the Capitol rises another 100 feet above the oculus. Follow the tour to reach the top!

Inside the Dome - Oculus Level - East Side

The enclosed room surrounding the oculus is for temperature and weather control. Many of the dome walls from here on up consist of thin galvanized metal sheets, making it very susceptible to temperature fluctuations. These changes can be very harmful to the Capitol’s decorative and plaster surfaces,

Inside the Dome - Oculus Level - South Side

The dome has not been open to visitors since the 1950s. The dangerously steep staircase to your right, that rises more than 30 feet from the rotunda dome, serves as the only entrance and exit for the exterior dome. To ensure the safety of all visitors, this area remains closed.

Between the Domes - 7th Level Stairs

The stairway only grows steeper and more confined as it descends toward the rotunda dome. Below you can see that you even have to duck under a window!

Inside the Dome - Oculus Level - West Side

The dome was constructed from 1877-1878. The main skeleton of the dome consists of cast iron trusses produced by the S.J. Creswell Ironworks Company of Philadelphia. If you look to your left, you’ll see several names of Creswell foundry workers engraved into the original ironwork.

Inside the Dome - Oculus Level - Spiral Stair

Note that the oculus, resembling an upside down cereal bowl, is suspended from the ceiling above it using cables. The bolts can be seen in the floor of the next level up.

9th Level

As mentioned earlier, the dome walls are thin sheets of galvanized metal, making them vulnerable to Michigan’s notoriously unpredictable weather. In some spots, such as this level, extra sheeting has been added along the interior walls to assist with condensation control.

Lantern Stair - Top

You’ve reached the top of the Capitol! Above you is the base of the finial, the tall spire that tops the dome. We hope you’ve enjoyed this virtual tour experience!
