Less than 20 miles to the south of Cairo, in Egypt's former capital Memphis, stands one the oldest pyramids in the world — the Step Pyramid of Djoser, also known as Zoser.
Djoser was built about 4,600 years ago, between 2667 and 2648 BC, and is the oldest large-scale stone monument still standing. According to the Los Angeles Times, the shimmering pyramid takes viewers' breath away, and that was the point.
It's situated in the Saqqara necropolis, which is the largest pyramid-related funerary complex in the world.
While the Great Pyramid of Giza is more famous, and the pyramids at Dahshur are bigger, they might never have existed had it not been for Djoser.

The pyramid was designed by his chief architect named Imhotep, possibly the world's first architect. Imhotep came up with a novel idea — build up. He decided to use six layers that got smaller as they ascended. And it formed, according to BBC, "a stairway to heaven."
It's about 200 feet high — tall enough to make the Pharaoh's ascent into heaven easier.
The limestone bricks also distinguished it. About 11.6 million cubic feet of stone and clay were used. Before this, buildings were made from wood, mud brick, and reeds.
In 1926, French architect Jean Philippe Lauer was the first person to excavate the pyramid. When the tunnels beneath the pyramid were first explored they were tiled in blue, to symbolize Djoser's afterlife.

In 2006, the Egyptian government announced it was going to restore it. A British engineering firm was hired, but it wasn't a simple task. To keep the pyramid from collapsing inwards, giant self-inflating airbags filled with liquid were inserted inside.
They had been developed by Peter James, a structural engineer, who first designed the airbags to absorb explosions while defusing bombs in Afghanistan.
To keep the pyramid together, steel rods were threaded through the steps diagonally in a way to ensure they weren't visible.
Despite the hard work and advanced technology, the restoration was put on hold for nearly two years, from 2011 to the end of 2013, over security concerns. Egypt was enduring uprisings that ended with the country's leader Hosni Mubarak being removed from office.

UNESCO experts criticized the restoration, so additional work was done that the organization later approved. The restoration was finally finished in 2020. It took 14 years, and cost nearly $6.6 million.
On March 5, Djoser was officially reopened. Dignitaries were served cold juices by bow-tied waiters.
At a press conference, Egyptian Prime Minister Mostafa Madbouli told reporters: "We are working hard to build a new Egypt ... and the restoration of our heritage is at the top of our priorities."
Tourists and reporters could finally enter the pyramid. Seeing what's hidden from the outside world was vital, according to History Revealed, because the subterranean structure was "a real wonder."

Tourists descended down narrow stairways.

The burial chamber and sarcophagus of King Djoser, which is 90 feet below the surface, was open to the public. New lighting had been added during the restoration, but from up above it didn't look too impressive.
But from the ground, it's more imposing. When Djoser was buried the opening was closed off with a 3.5-ton block of granite.
Tourists also climbed the staggered sides of the pyramid.
