The nine-year project to restore the grave of the ancient Egyptian King Tutankhamen came to an end.
Specialists from the Getty Conservation Institute restored the scratches and abrasions on the wall paintings caused by visitors to the burial chamber.
New ventilation system should reduce the need for subsequent cleaning.
The new fences will restrict direct access to the paintings, while the new observation platform, the lighting and the signage will allow visitors to better see the tomb and recognize its historical and cultural significance.
Experts also came to the conclusion that the brown spots found on the wall paintings were growths left by microbes that had long since died.
The stains were not removed because it was discovered that they were absorbed into the paint coat.
Although most of the items are currently in the Egyptian Antiquities Museum in Cairo, visitors to the grave can still see Tutankhamen’s mummy, the outermost wooden coffin and quartzite sarcophagus, as well as paintings depicting his life and death.
