Tourists and history lovers will soon be able to experience Rome’s famed Colosseum in a new (or actually very old) way—standing on its floor!

Ancient Romans built the Colosseum in 80 a.d. They used the massive outdoor arena to stage fighting contests. After four centuries of heavy use, the structure fell into disrepair. Then it was used as a rock quarry for more than 1,000 years.

In the early 19th century, archaeologists removed the Colosseum’s floor to study the tunnels beneath it. Now, engineers are working to create a new, high-tech floor. They’ll use rotating wood slats, which will allow visitors to peek through the floor to the areas below.
