>> The Boy King is back where he belongs. Almost a century ago, this tomb was discovered in Egypt, the resting place of 3,000-year old mummified pharaoh, Tutankhamen. And now, the burial site's reopened after a painstaking renovation project by an LA-based conservation institute.>> And that's an incredibly precious object.
So, it was a very stressful time to safely move the mummy. Then, the case had to be brought out and the glass retreat. And the base of the case weighs about, maybe, 250 kilos, it's steel. And the antiquities personnel moved it. They took it up the ramp. It was terrifying, 12 men chanting and carrying it up the ramp.
I said if one slips, it will slide, and will kill somebody. They said don't worry.>> Over ten years, the intricate frescoes were restored to the pristine state they were in when British archaeologist, Howard Carter, first entered in 1922. The project was temporarily delayed by political upheaval in 2011 when protests forced President Hosni Mumbarak from power.
The team of conservationists, architects, environmental specialists and scientists have their work cut out. Decades of dust, damp and visitors had damaged the ancient grave in the Valley of the Kings.>> You can't attach to the floors, the ceiling and the wall, so you have to design all of these components to be self-supporting in a way so that they don't damage any historically significant features.
So you have to be very clever in how you detail them because they have to support themselves, and they have to be quite strong and robust. Even water vapor produced by visitors breathing had affected everything inside the tomb. A new system means air is now completely refreshed every 30 minutes, perfect conditions for the next 100 years.
