Pyramids Of Giza

In 1954 an Egyptian archaeologist named Kamal el-Mallakh was clearing rubble along the south side of the Great Pyramid when he noticed a line of enormous limestone blocks set into the bedrock. They were a lid. Beneath them lay a pit, sealed for roughly four and a half thousand years, and inside the pit was a ship. It had been taken apart into more than a thousand pieces of cedar and packed in neatly, oars and all. The wood was still sound. When the pieces were eventually reassembled, the boat measured over forty metres long.

Nobody knows for certain why it was buried there. The most common reading is that it was meant to carry the dead king across the sky. Whatever its purpose, it is the oldest intact ship on Earth, and it was parked beside the oldest of the Seven Wonders.

Twenty Years, Twenty Thousand People

The Great Pyramid was built for Khufu, a pharaoh of the Fourth Dynasty, around 2600 BC, and most estimates give the job about two decades. The two other large pyramids on the plateau belong to his son Khafre and grandson Menkaure. Khufu's was about 146 metres tall when finished; it has lost its capstone and outer casing since, and stands closer to 138 today. It held the title of tallest structure on the planet for something like 3,800 years, until the spire of Lincoln Cathedral passed it in the fourteenth century.

Herodotus, visiting in the fifth century BC, reported that a hundred thousand slaves built it. That number survived for two millennia. Then, in the 1990s, excavators uncovered the workers' settlement just south of the pyramids: bakeries that produced bread on an industrial scale, dormitories, rubbish heaps full of cattle bone, and cemeteries where labourers were buried with healed fractures that show they had received medical care. These were paid crews, fed well, and interred in the shadow of the thing they built. Current estimates put the workforce at perhaps twenty thousand at any one time.

A more recent find put names to the logistics. In 2013, at Wadi al-Jarf on the Red Sea coast, archaeologists found papyri that turned out to be the logbook of a foreman called Merer, recording how his crew ferried limestone from the Tura quarries across the Nile to a site they called "the Horizon of Khufu." They are the oldest inscribed papyri ever found, and they are essentially a shipping manifest.

What Time Did To It

When new, the Great Pyramid was smooth and white, sheathed in polished Tura limestone. The stepped, sandy-coloured surface you see today is the core masonry. An earthquake in 1303 loosened much of the casing, and over the following centuries it was stripped and carted off to build mosques and walls in Cairo. The cap of smooth stone still clinging to the top of Khafre's pyramid is the only hint of how all three once looked.

In the ninth century, the Abbasid caliph al-Ma'mun had his men tunnel into the north face because they could not find the original entrance. That forced passage is the one visitors use today. When they reached the burial chamber they found Khufu's granite sarcophagus in place and empty. Whoever emptied it, and when, is not recorded.

In 1798 Napoleon fought the Mamluks within sight of the plateau. The scholars he brought along began the systematic documentation of Egypt that, more or less, founded Egyptology as a discipline.

Still Hiding Rooms

In 2017, a team using muon detectors, which track cosmic-ray particles passing through stone, announced a previously unknown void above the Grand Gallery inside the Great Pyramid, at least thirty metres long. In 2023 a nine-metre corridor just behind the north face was confirmed with an endoscope camera. Neither has been entered. The most studied building in human history still has spaces no living person has stood in.

And one more small thing: the pyramid's sides are aligned to true north with an error of only a small fraction of a degree, achieved without a compass, using stars and shadows. Exactly how is still argued over.

Now

The Giza necropolis has been a UNESCO World Heritage Site since 1979 and is managed by Egypt's Ministry of Tourism and Antiquities. Khufu's boat was moved in 2021 to the Grand Egyptian Museum, built at the edge of the plateau, which fully opened in 2025.

The pressure today comes from the city rather than the desert. Giza is part of greater Cairo, and apartment blocks run right up to the edge of the site. Look west and you get the empty-desert postcard; turn around and the suburbs start. Pollution, rising groundwater and the sheer volume of visitors wear at the stone. The pyramids have outlasted every civilisation that visited them. Now they share a neighbourhood with twenty million people.
