Egypt inaugurated the Grand Egyptian Museum on Saturday in a lavish ceremony near the Giza Pyramids.
The event drew presidents, prime ministers, and royalty from around the world.
Construction of the $1 billion complex, funded largely by Japanese loans, began two decades ago but faced delays from political upheaval, a pandemic, and regional conflicts.
The museum aims to house one of the world's richest antiquities collections in a contemporary setting.
The opening featured dancers in pharaonic attire, pop stars, an international orchestra, lasers, fireworks, and a drone light show forming hieroglyphics and ancient gods.
Egyptian President Abdel Fattah al-Sisi described it as writing a new chapter for the nation.
Attendees included German President Frank-Walter Steinmeier, Dutch Prime Minister Dick Schoof, Hungarian Prime Minister Viktor Orban, Palestinian President Mahmoud Abbas, and crown princes from Oman and Bahrain.
Prime Minister Mostafa Madbouly called the museum a gift to the world from a civilization over 7,000 years old.
The museum displays the full Tutankhamun collection for the first time since 1922, including the golden mask, throne, and sarcophagus.
A colossal Ramses II statue now greets visitors in the entry hall.
Spanning 120 acres with sleek pyramid-evoking design, it contrasts the outdated downtown Egyptian Museum, which suffered looting in 2011 and damage to artifacts.
Officials expect 5 million annual visitors to boost tourism, vital for Egypt's economy, targeting 30 million by 2032.
The project joins other mega-initiatives to revive foreign currency inflows amid past instability.
