A wall between two roofless spaces inside the Pompeii archaeological park collapsed this afternoon, UNESCO announced.
Pompeii Park is the third most popular tourist site in Italy, after the Colosseum and the Forum.
Last year, it was visited by 2,6 million people.
The collapse happened in a part that is not open to the public.
Pompeii was a large Roman city destroyed by the eruption of Mount Vesuvius on August 24, 79 AD, in which two thousand people died, and the location remained undiscovered for over 1.600 years due to the ashes.
