Rome's Colosseum, site of violent gladiator battles, to get new high-tech floor
Rome's ancient Colosseum, the famous arena where gladiators and wild animals once clashed in violent combat, will soon have a new retractable floor built over its center.
"You will be able to walk on it and go to the center of the Colosseum, seeing it in the same way as visitors used to up to the end of the 19th century," the Italian Culture Minister Dario Franceschini said at a press conference on Sunday (May 2), Reuters reported. Archaeologists removed the last arena floor in the early 19th century, in order to excavate and restore the network of secret tunnels below, and the floor was never fully replaced, The Guardian reported.
The Ministry of Culture just granted a $22.2 million (18.5 million euro) contract to the Italian engineering firm Milan Ingegneria to design the new floor, and announced that the project should be completed by 2023. The 32,300-square-foot (3,000 square meters) floor will be made of hundreds of wooden slats that can be rotated to let light and air into the chambers below, BBC News reported.

This network of underground tunnels and chambers, called the hypogeum, once held wild animals, slaves and criminals before their battles commenced on the floor above, according to Smithsonian Magazine. Pulleys, elevators and ramps allowed the organizers of the games to lift the gladiators and animals into different areas of the arena, surprising spectators and building suspense during the games.

Soon, the new floor will be able to shield the hypogeum from inclement weather, while also allowing the city to host cultural events at the amphitheater.
"The arena will be used for high culture, meaning concerts or theater, but no gladiator shows," archaeologist Alfonsina Russo, director of the Colosseum and the associated archaeological park, told The Times in December 2020.

"It's another step forward toward rebuilding the arena, an ambitious project that will aid the conservation of the archaeological structures while getting back to the original image of the Colosseum," Franceschini said on Sunday, according to BBC News.
