The ceremony, designed to showcase the country's rich heritage, will snake along the Nile corniche from the Egyptian Museum overlooking Tahrir Square, to the newly opened National Museum of Egyptian Civilization in the Fustat neighborhood, where Egypt''s first Islamic capital was located.

The mummies are being transported in climate-controlled cases loaded onto rucks decorated with wings and pharaonic design for the hour-long journey from their previous home in the older, Egyptian Museum.

The ceremony kicks off with a 21-gun salute and will be accompanied by lights and music.

Most of the mummies belong to the ancient New Kingdom, which ruled Egypt between 1539 B.C. to 1075 B.C., according to the ministry of antiquities.

They include Ramses II, one of the country''s most famous pharaohs, and Queen Hatshepsut, Egypt''s only woman Pharaoh — who wore a false beard to overcome tradition requiring women to play only secondary roles in the royal hierarchy.

The mummies — 18 pharaohs and four other royals — were originally buried around 3,000 years ago in secret tombs in the Valley of Kings and the nearby Deir el-Bahri site. Both areas are near the southern city of Luxor. The tombs were first excavated in the 19th century.

After excavation, the mummies were taken to Cairo by boats that sailed the Nile. Some were showcased in glass cases, while others were stored. The remains of Ramses II were taken to Paris in 1976 for intensive restoration work by French scientists.

The parade is part of Egypt''s efforts to revive a tourism industry that has been reeling from the political turmoil following the 2011 popular uprising that toppled longtime autocrat Hosni Mubarak, and more recently, the coronavirus pandemic.

“This parade is a unique global event that will not be repeated,” declared Tourism and Antiquities Minister Khaled el-Anany.

Security is tight in the capital, with authorities closing off major streets and intersections all along the route for the slow-moving vehicles. Guards on horses and Egyptian celebrities and signers followed the motorcade.

“Again, Egypt dazzles the world with an unrivalled event,” said movie star Hussein Fahmy in an official promotional video.

The event is scheduled to begin at sunset, and will be broadcast live on the country''s state-run television and other satellite stations. The Tourism and Antiquities Ministry is also live-streaming it on social media platforms.

The “Pharaohs'' Golden Parade” beings at Tahrir, where authorities officially unveiled an obelisk and four sphinxes to now decorate Cairo''s most famous square.

Egypt''s President Abdel Fattah el-Sissi, who will welcome the mummies at the new museum, tweeted: “This majestic scene is a new evidence of the greatness of this people, the guarding of this unique civilization that extends into the depths of history.”Once at the new museum, 20 of the mummies will be displayed, while the remaining two will be stored, according to the ministry.
