Scientists reveal hidden passage in the large pyramid

Scientists who work on revealing the secrets of the great pyramid of Egypt have found a hidden round that could lead to new discoveries, the authorities announced on Thursday.

The passage is 30 feet long and more than two and a half foot wide, said the Ministry of Antiquity in an explanation.

The Egyptian Minister of Tourism and Antiques, Ahmed Issa, said reporters at the ancient site in Gizeh, which is also known as Khufu or Cheops pyramid that the "gable corner" was found with a triangular blanket "on the north side of the king's great pyramid.

The discovery was part of the Scanpyramid project, which was started in 2015 as a collaboration between major universities in France, Germany, Canada and Japan and a group of Egyptian experts.

The archaeologist Zahi Hawass, Egypt's former minister of antiquities, leads the committee that monitors the project, uses the advanced technology to make hidden parts of the interior of the pyramid visible without having to dig it out.

The technology is a mixture of infrared thermography, myon radiography imaging and 3D reconstruction-according to the researchers, all are non-invasive and non-destructive techniques.

The large pyramid is the largest in Giza and the only preserved building of the seven wonders of antiquity with a height of 479 feet.

It was built about 4,500 years ago, has three known chambers and, like other pyramids in Egypt

Mr. Hawass told reporters in the pyramid on Thursday that "there is a great option ... that the tunnel protects something. In my opinion, he protects the actual burial chamber of King Khufu".

2017 scan pyramid announced the discovery of a cavity the size of a passenger plane. It was the first major structure that has been found within the great pyramid since the 19th century.

experts are disagreed with how the pyramids were built, so that even relatively small discoveries cause great interest.

The authorities often advertise publicly to attract more tourists, an important foreign currency source for this financially stricken country in the Middle East.

The Egyptian tourism sector suffered a long downturn after the political unrest and violence after the uprising of 2011, which displaced the long-time autocratic president of the country, Hosni Mubarak, as well as further setbacks after the outbreak of the Coronavirus pandemic.
