Great Pyramid: what it is
The Great Pyramid is the oldest of the Seven Wonders of the Ancient World and the only one still standing. It was built for Khufu, second king of Egypt's Fourth Dynasty, at the peak of a century of experiments in pyramid building that began with Djoser's step pyramid.
What you see today is the stepped core. The smooth outer skin of white Tura limestone was stripped in the Middle Ages, which also took away the top few metres; the pyramid now stands about 138.5 metres tall.

- 01
Precision on a huge scale
The base covers about 5.3 hectares and is almost perfectly level and square. Its sides are aligned to true north, south, east and west with remarkable accuracy, probably by sighting stars.
- 02
Three chambers and a gallery
A descending passage leads to an unfinished chamber cut into the bedrock. An ascending passage opens into the Grand Gallery, a corbelled hall about 8.6 metres high, which leads to the granite King's Chamber.
- 03
Engineering the weight
Above the King's Chamber, five stacked compartments topped by a pointed roof of limestone beams spread the load of the masonry above — an early solution to building a void under millions of tonnes of stone.
- 04
A shining surface
The casing stones were cut so finely that the pyramid would have looked like a single smooth, bright form. A few casing blocks still survive at the base.
Construction timeline
Work begins early in Khufu's reign on the Giza plateau.
The pyramid is finished; Khafre's and Menkaure's pyramids follow nearby.
Caliph al-Ma'mun's workers tunnel into the north face — the entrance most visitors still use.
Casing stones are removed for building in Cairo, after an earthquake in 1303 loosened many.
Papyri found at Wadi al-Jarf, the oldest inscribed papyri known, record an official named Merer shipping Tura limestone for Khufu's pyramid.
The ScanPyramids project detects a large void above the Grand Gallery and confirms a hidden corridor behind the north face.
How the design changed
From white to gold-brown
Losing its casing changed the pyramid's look completely: from a smooth, glowing geometric form to the stepped, weathered profile we know.
A new way in
The original entrance on the north face was sealed. Visitors today enter through the tunnel forced in the 9th century, then join the original ascending passage.
Who built it
Ancient sources and later tradition name Hemiunu, Khufu's vizier and a relative, as the overseer of the work. Excavations of a workers' town south of the plateau show that the builders were organised, fed and paid crews of Egyptians, not slaves, and their own tombs lie nearby. The Wadi al-Jarf papyri give a rare first-hand logbook of the logistics.

Great Pyramid: questions people ask
When was the Great Pyramid built?
It was built during the reign of Khufu, around 2600–2560 BCE. Most Egyptologists date its completion to about 2560 BCE.
How tall is the Great Pyramid?
It was originally about 146.6 metres (481 feet) tall. After losing its casing and capstone it now stands about 138.5 metres.
Who built the Great Pyramid?
Organised crews of paid Egyptian workers built it for Pharaoh Khufu, with the vizier Hemiunu traditionally credited as overseer. Workers' tombs and a workers' town have been excavated at Giza.
Why was the Great Pyramid white?
It was cased in polished white Tura limestone. Most of the casing was removed in the Middle Ages for building in Cairo, exposing the rougher core blocks.
