Teacher: Now, understand the problem? Solve this instance: Real estate developers using heavy machinery tore down a 20-foot (6-meter) tall pyramid at the oldest archaeological site near Peru's country's capital, cultural officials said Wednesday. 
  
 Rafael Varon, deputy minister of cultural patrimony, told reporters the destruction occurred over the weekend at the ruins of El Paraiso, a few miles (kilometers) north of Lima. 
  
 He said Wednesday his agency has lodged criminal complaints against the two companies for the weekend's damage, identified as the Alisol and Provelanz, and has moved to seize the equipment used. People who answered the telephone at both companies said no one was available to comment. 
  
 Peru's tourism ministry says El Paraiso was built some 4,000 years ago and was a religious and administrative center, long before the rise of the Inca culture encountered by the Spanish conquerors. 
  
 Marco Guilen, director of an excavation project at El Paraiso, said the people who tore down the pyramid "have committed irreparable damage to a page of Peruvian history." 
  
 "We are not going to be able to know in what ways it was constructed, what materials were used in it and how the society in that part of the pyramid behaved." 
  
 Varon said people apparently working for the two companies tore down one pyramid and tried to destroy three others, but were stopped by witnesses. 
  
 Mayor Freddy Ternero from the town where the ruins are located, San Martin de Porres, said the pyramids were located in agricultural fields and were not guarded, though he said the Minister of the Interior sent police to protect it after the incident. ||||| Image caption A picture released by the culture ministry showed the area cleared by heavy machinery 
  
 Authorities in Peru say an ancient pyramid at the oldest archaeological site near the capital, Lima, has been destroyed. 
  
 They are pressing criminal charges against two real-estate companies blamed for tearing down the structure, which was 6m (20-ft) high. 
  
 An archaeologist said those responsible had committed "irreparable damage". 
  
 The building was one of 12 pyramids found at the El Paraiso complex and is thought to be at least 4,000 years old. 
  
 The site, which dates back to the Late Preceramic (3500-1800 BC) period, is situated several kilometres north of Lima. 
  
 We are not going to be able to know in what ways it was constructed, what materials were used in it and how the society in that part of the pyramid behaved Marco Guilen , Director of excavation project, El Paraiso 
  
 According to Peru's tourism ministry, it was a religious and administrative centre long before the pre-Columbian Inca civilisation. 
  
 Rafael Varon, deputy minister of cultural patrimony, said the destruction had taken place over the weekend. He said company workers using heavy machinery had attempted to destroy three further pyramids, but had been stopped by onlookers. 
  
 Mr Varon said criminal complaints had been lodged against two companies. 
  
 Marco Guilen, director of an excavation project at El Paraiso, told Associated Press news agency the people who tore down the pyramid "have committed irreparable damage to a page of Peruvian history".

Peruvian authorities say a pair of real-estate developers have ruined a 4,000-year-old pyramid, and they're facing criminal charges, the BBC reports. "Irreparable damage" was done to the 20-foot-high pyramid, says an archeologist. The El Paraiso complex, near Lima, had 12 pyramids; the companies tried to tear down three others before witnesses stopped them. El Paraiso was a religious and administrative area dating much earlier than the Incas, experts say. Now, "we are not going to be able to know in what ways it was constructed, what materials were used in it, and how the society in that part of the pyramid behaved," the archeologist tells the AP. (In more encouraging archaeological news, researchers in Peru made an exciting find recently.)
