JUST when Greece thought it had come through the worst of the economic crisis, it was hit by a new blow — one of its most famous landmarks, the Acropolis, is crumbling. 
  
 Engineers have discovered that part of the huge flat-topped rock on which the ancient Parthenon sits in the centre of Athens is starting to give way, the Greek news agency ANA said. 
  
 The Parthenon is a temple dedicated to the goddess Athena, whom the people of Athens considered their patron. 
  
 Construction began in 447BC when the Athenian Empire was at the height of its power. 
  
 Teams from the Central Archaeological Council found “instability over quite a wide area” of the Acropolis after investigating a rockfall in January in which a boulder of “considerable size” tumbled from the most visited site in the Greek capital.

 Work to shore up the southern slope of the hill on which the 2,500-year-old temple complex sits will be necessary, the agency reported, blaming rainwater pipes from the old Acropolis museum. 
  
 Despite sharp cuts elsewhere, the restoration work on the site that has been going on since the 1970s has remained sacrosanct, a symbol of the country’s glorious past. 
  
 In the not so glorious present, Greece has had to endure six years of brutal recession, with unemployment soaring to 27 per cent. 
  
 And the Acropolis is not the only ancient world monument at risk of demise. 
  
 The oldest pyramid in Egypt — the Pyramid of Djoser — is being destroyed by the company hired to restore it, according to activists. 
  
 According to the Non-stop Robberies movement, the company hired by Egypt’s Ministry of Antiquities to restore the pyramid, in the ancient burial ground of Saqqara, has broken preservation laws requiring that any new construction be less than 5 per cent of the preserved structure. 
  
 Instead the company — which has reportedly never worked on a preservation project before — built a number of new walls and structures that passed the limit. 
  
 The company, called Shurbagy, has been working for nine years and has not been successful in any of the six projects it has worked on, the movement’s Amir Gamal told the Egypt Independent last month. 
  
 “The company has never restored any archaeological site. All projects it had were to create modern construction at archaeological sites,” Gamal said. ||||| Step pyramid of Djoser at Saqqara in Egypt is reported damaged during restorations, UNESCO seeks answers

 UNESCO has asked Egypt for a detailed report on restoration work carried out at the Djoser pyramid following reports the more than 4,600-year-old monument had been damaged. 
  
 Egyptian media reported earlier this month that the pyramid, which dominates the necropolis of Saqqara, south-west of Cairo, had been damaged during the restoration work. 
  
 "The UNESCO World Heritage Centre sent a letter to the ministry of antiquities requesting a detailed technical report on the work," said Tamar Teneishvili, a senior official from UNESCO in Cairo. 
  
 "This request was made after information gathered from the media." 
  
 She said UNESCO would wait for the ministry's report to decide on its future plans. 
  
 UNESCO has also asked if its own 2011 recommendations on the restoration of the pyramid had been followed.

 Several Egyptian experts have criticised the restoration work, saying the monument's original facade had been altered. 
  
 Some specialists also said the company hired to do the restoration work, Al-Shurbagy, did not have the necessary experience. 
  
 Antiquities minister Mamdouh al-Damati said the criticism was "baseless". 
  
 Last week he told a group of journalists invited to see the ongoing restoration that the "work is underway without a problem". 
  
 The executive director of the project, Michel Ghobrial Farid, also rejected the criticism, saying the pyramid's appearance was restored the way it was at the time of its construction. 
  
 The project started in 2006 but was interrupted in February 2013 due to a lack of funding. 
  
 The tomb, built by the master architect Imhotep for the pharaoh Djoser, originally stood 62 metres tall and is considered the oldest building in the world built entirely of stone.

 First posted ||||| The Acropolis is falling down and will need significant work to shore it up, archaeologists have warned. 
  
 Engineers have found that a section of the huge flat-topped rock on which the ancient Parthenon sits in Athens is beginning to give way, the Greek news agency ANA has said. 
  
 The ancient citadel located on a high rocky outcrop above the Greek capital contains the remnants of some of the world's most historic ancient buildings, the most famous being the temple Parthenon. 
  
 Teams from the Central Archaeological Council found "instability over quite a wide area" after investigating a rockfall in January in which a boulder of "considerable size" tumbled from the most visited tourist site in Greece. 
  
 Work to secure the southern slope of the hill on which the 2,500-year-old temple complex sits will be necessary and archaeologists have blamed rainwater pipes from the old Acropolis museum. 
  
 There is evidence that the Acropolis was inhabited as far back as the fourth millennium BC, but it was Pericles in the fifth century BC who coordinated the construction of the site's most important buildings: the Parthenon, the Propylaia, the Erechtheion and the temple of Athena Nike. 
  
 Construction on the Parthenon began in 447BC when the Athenian Empire was at the height of its power. 
  
 Despite sharp cuts elsewhere, the restoration work on the site that has been going on since the 1970s has remained sacrosanct. 
  
 Greece has endured six years in a recession, with unemployment soaring to 27%. For the first time since 2008 it is expected to see growth of around 0.4% this year, The Times reported. 
  
 The Acropolis is not the only ancient world monument under threat of collapse. Activists have claimed the Pyramid of Djoser, the oldest pyramid in Egypt in the ancient burial ground of Saqqara, is being destroyed by the firm hired to restore it. 
  
 According to the Non-stop Robberies movement, the company hired by Egypt's Ministry of Antiquities to restore the pyramid – called Shurbagy - has broken preservation laws requiring that any new construction be less than 5% of the preserved structure. 
  
 In March, further collapses in the ancient Roman city of Pompeii were reported amid calls for more restoration funding for the UNESCO world heritage site. |||||
Output:
Greece's famous Parthenon could be in danger of coming down 2,500 years after it was put up at the height of the Athenian Empire. Archaeologists have discovered "instability over quite a wide area" of the Acropolis, the flat-topped rock that holds the weight of the ancient structure, news.com.au reports, citing Greek news outlet ANA. Archaeologists investigating the site after a rock of "considerable size" fell in January found the fault, which they now blame on rainwater pipes from an old Acropolis museum. The scientists say plenty of restoration work will need to be added to that already being completed at Greece's most-visited tourist destination. Restoration work has been ongoing at the site despite Greece's recent trudge through a recession with the unemployment rate at 27%, the International Business Times reports. As if one ailing monument isn't enough, activists also fear for Egypt's oldest pyramid. Shurbagy, a company hired to restore the 4,600-year-old Pyramid of Djoser at Saqqara, is instead destroying it, say activists, who argue Shurbagy has built new walls and structures at the site in clear disregard of preservation laws that limit new construction to less than 5% of the restored structure. UNESCO has asked for a detailed report on the restoration from the the Ministry of Antiquities, ABC News previously reported.
