Giza pyramids to be protected by high tech 12 mile long fence

The modernisation of the ancient pyramids at Giza has begun with the building of a high-tech security fence. The £14m project at the World Heritage Site includes CCTV, security alarms and sensors to alert guards about peddlers encroaching on the area and harassing tourists. The 12-mile fence is the first stage to update the last remaining ancient Wonder of the World; visitors will now arrive at the c.2575 BC site near Cairo through security gates with x-ray machines
