Inside and out, architects, preservationists and scores of skilled tradespeople have given their full attention to one of the city’s most iconic Art Deco masterpieces – Union Terminal. The former train station, now home to the Cincinnati Museum Center, received its first full structural overhaul, updating infrastructure and repairing the building’s skeleton and exterior fabric. 

“We’re so excited to show the community what we’ve been working toward these past two-and-a-half years,” said Elizabeth Pierce, president and CEO of Cincinnati Museum Center. “Not only have we restored a National Historic Landmark, preserving it for future generations, we’ve reimagined a new robust museum experience. This community is in for an epic adventure, and we’re so glad to welcome them home.”

The museum officially reopens to the public Nov. 17. In addition to the reinvigorated galleries, there will be new food and retail services, with draft beer on tap making its first appearance. The OMNIMAX Theater will reopen in late December. 

During the two-year $213 million reboot, the Cincinnati Museum Center told its story in construction updates and listed some staggering and fascinating numbers, which we’ve compiled here.

  • More than 225,000 square feet of limestone, brick, terra-cotta and concrete were cleaned and repaired.
  • Over 35,000 linear feet (or about 6.5 miles) of silicone caulking were removed and replaced with mortar closely matching that of the original.
  • Crews rebuilt the curved drum walls that sit just beneath Union Terminal’s half dome. In particular, the interior wall was replaced with a reinforced concrete block wall and covered with over 17,500 original exterior face bricks.

Union Terminal’s cascading fountain and plaza were removed to expose the roof deck underneath for water damage repairs and waterproofing. The area was then rebuilt. 

  • Fifty-six concrete trucks were needed to pour the basin of the 8,000-square-foot fountain, which holds 44,000 gallons of water.
  • Two-part polyurea waterproofing was applied.
  • Crews added a finishing layer of green terrazzo with a rustic finish, matching the 1933 original.
  • Crews waterproofed 120,000 square feet of plaza. 
  • The project required 450 cubic yards of concrete.

Six months of construction addressed steel girders damaged by decades of water penetration. Eight 40-foot steel beams were brought in and hoisted from the lower level to the mezzanine, then glided into place using compressed air. The gantry systems and scaffolding for this installation alone required 20 tons of steel.

  • Three new centrifugal glycol chillers
  • Three hot water boilers
  • Two steam boilers

  • One year of restoration was needed to update and repair mechanisms in the clock on the building’s facade. 
  • The two hands were removed and restored, with new red neon lighting along the edges. 
  • New red and amber glass was installed across the 18-foot face.

  • Rotunda elevators now replicate historic storefronts that once served as gateways to shops and offices in 1933.
  • Yellow, orange and silver bands of the ceiling, towering 106 feet overhead, have been cleaned, patched and painted. 
  • Red Verona marble walls of the rotunda and concourse have been polished and cleaned, as have the aluminum strips and metalwork accents.
  • New terrazzo floors in the Losantiville Dining Room echo the serpentine pattern of a long-ago lunch counter. 
  • Twenty-two original canvas murals that ringed the top of the dining room were restored and returned to the space for the first time in over 30 years.
  • It took six months to clean and repair over 6,500 square feet of historic Winold Reiss glass-tile mosaic murals.
  • Thousands of terra-cotta tiles have been cleaned; plaster ceilings have been repaired and painted; and restored windows and light fixtures have been reinstalled.
  • About 5,200 gallons of paint were used across Union Terminal’s historic, gallery and office spaces. 


Dinosaur Hall

The dinos are back, and they’re ready to roar. Filled with important and visually impressive fossils and skeletons, many of which are at the center of groundbreaking research projects, Dinosaur Hall will introduce fundamental principles of evolution and give visitors a look at the creatures who roamed our world more than 230 million years ago.

Look for: giant plant-eater Galeamopus (60 feet long), the tyrannosaurid Daspletosaurus (36 feet long) and the most-complete-of-its-kind Torvosaurus (35 feet long).

The Cave 

Dark, dank and oh-so-chilly, the original cave featured many of the characteristics of the real thing. Expect a state-of-the-art experience with updated technology for such features as that damp cave feel, lighting and cold-temperature effects. 

Look for: a waterfall, an underground stream and a live Big Brown Bat colony on the advanced trail. Beginner’s trail is wheelchair-accessible.

Public Landing

All aboard! Your steamboat awaits. This immersive experience of the sights and sounds in 19th century Cincinnati allows visitors to explore the Public Landing and the stories told through its collections. Technology updates enhance the experience, though actual time travel has yet to be achieved.

Look for: new artifacts, improved access and new storefront entryways to other galleries.
