ROME, Italy: In an important step to renovate the Roman Colosseum, a new floor, is to be installed.
The Colosseum remains Italy's most visited site, with 7.6 million visitors in 2019.
In the early 1800s, the floor was removed to provide a view of the underground passageways under the Colosseum.
The Colosseum was built nearly 2,000 years ago in 80 A.D.
An Italian engineering firm, Milan Ingegneria, has budgeted $22 million to replace the floor, which is scheduled to be completed by 2023.
"One more step forward toward the reconstruction of the arena, an ambitious project that will help preserve and protect archaeological structures, while recovering the original image of the Colosseum and also giving it back its nature as a complex stage machine," Italy's Ministry of Culture said in a statement.
To be made of Acoya wood, the flooring will undergo a process that increases resistance and durability, along with sustainability.
"The complex underground system under the wooden pavement, thanks to hatches, hoists and mobile types of machinery, allowed men, beasts and props to be brought up to the arena floor," Colosseum director Alfonsina Russo said, according to CNN.
