Problem:Image caption Pompeii is one of the world's greatest archaeological treasures 
  
 A woman from Canada has handed back a piece of ruins from the ancient city of Pompeii more than 50 years after she first took it. 
  
 The woman picked up a small decoration, which was part of a theatre entrance, during her honeymoon in Italy. 
  
 She put it in her bag and took it back with her to Montreal. 
  
 Pompeii is one of Italy's most visited sites. A sudden eruption of Mt Vesuvius in 79 AD buried and largely preserved the town under ash. 
  
 The woman - who has not been named - kept it with her for half a century but clearly her actions nagged away at her. So this month she travelled back to Italy to hand back the fragment. 
  
 Captain Carmine Elefante, who runs the police's Cultural Heritage Protection Group in Naples, says that the woman - now in her 70s - was in tears when she gave it back. 
  
 "This has no precedents, the fact that someone was pushed by the weight of their conscience to hand back what they had taken," he told me. 
  
 He said that though the fragment was not enormously valuable, "it was an element of ornament at the quadriporticus [rectangular open area] in Pompeii, where everything has its value". 
  
 "It is a testimony of past civilisations," he added. 
  
 The woman did not receive a fine. The police say they hope her actions will encourage others who may have taken off with pieces of Pompeii to do the same. ||||| A Canadian woman has given back a Pompeii relic she stole 50 years ago. 
  
 The 70-year-old woman from Montreal stole a piece of the Roman city ruins during her honeymoon in the Italian region of Campania, in 1964. 
  
 According to Italian newspaper Il Mattino, the Italian-American woman, who has not been named, put the artefact in her bag and took it back with her to Canada and also to Beijing, where she moved a few years later. 
  
 The woman said she has always felt guilty about the "souvenir" she had taken and therefore she decided to fly to Italy to give back the relic, part of an ancient theatre construction. 
  
 "I regret what I did, I want to remedy," the paper quoted her as saying. 
  
 Police, led by Captain Carmine Elefante, took the relic and gave it to local authorities, who will place it where it originally was. 
  
 The artefact is in good condition, authorities said. 
  
 Last September, two American tourists were caught with a 30kg artefact from Pompeii ruins in one of their suitcases. They were stopped at the Fiumicino airport, Rome, and charged with appropriation of state heritage. 
  
 The incident occurred shortly after a Canadian tourist tried to rob a piece of Rome's Colosseum. |||||
Solution:
It's been more than half a century since a certain unidentified Canadian woman took a piece of Pompeii home with her, but it seems her guilt got the better of her: She has finally brought it back to the site, the BBC reports. The woman was on her honeymoon when she picked up a decoration from a theater entrance in the ancient city, which was covered in volcanic ash in 79 AD. Now, the woman is in her 70s. "I regret what I did. I want to remedy (it)," she tells an Italian paper, via the International Business Times. "This has no precedents, the fact that someone was pushed by the weight of their conscience to hand back what they had taken," says an official in Naples. The object wasn't necessarily priceless in itself, but "it was an element of ornament at the quadriporticus (rectangular open area) in Pompeii, where everything has its value," the official says, per the BBC. It's still in good condition, the Business Times reports. The woman won't be fined; instead, officials hope others who have taken items from the site will follow her example. (Pompeii continues to offer new findings: Thanks to work at the site, researchers recently learned that Romans ate giraffe.)
