Experts say ancient building has started to tilt, with south side 40cm lower than north, and may need urgent repairs
The ancient Colosseum in Rome is slanting about 40cm lower on the south side than on the north, and authorities are investigating whether it needs urgent repairs.
Experts first noticed the incline about a year ago and have been monitoring it for the past few months, Rossella Rea, director at the 2,000-year-old monument, said in the Italian daily Corriere della Sera.
The Leaning Tower of Pisa, another of Italy’s most popular attractions, was reopened in 2001 after being shut for more than a decade as engineers worked to prevent it from falling over and to make it safe for visitors.
Rea has asked La Sapienza University and the environmental geology institute IGAG to study the problem and report back in a year.
Tests have begun to observe the effects that traffic on nearby busy roads may have on the monument.
