The Great Pyramid of Giza, also known as the Pyramid of Khufu, is the oldest and only surviving Wonder of the Ancient World, located on the Giza plateau near Cairo.

About this subject

The Great Pyramid of Giza was built around 2560 BCE as the tomb of Pharaoh Khufu (Cheops) of the Fourth Dynasty. Originally 146.6 meters tall, it now stands 138.8 meters due to the loss of its white limestone casing. Its square base measures 230 meters on each side, and it is estimated to consist of about 2.3 million stone blocks, each averaging 2.5 tons. The exact construction techniques remain debated by engineers and archaeologists.

The monument is located on the Giza plateau, west bank of the Nile, alongside the pyramids of Khafre and Menkaure and the Great Sphinx. The funerary complex includes temples, ramps, and solar boats. The pyramid has a precise astronomical alignment with the cardinal points, with minimal error.

Inside, the pyramid houses the King's Chamber, the Queen's Chamber, and passages like the Grand Gallery. The granite blocks in the chambers were transported from Aswan, over 800 kilometers away. The outer limestone casing was removed over centuries for use in Cairo's buildings. It is the only Egyptian pyramid with both ascending and descending passages, and its engineering is considered a masterpiece.

The Great Pyramid attracts millions of visitors annually and has been a UNESCO World Heritage Site since 1979. Modern studies, such as muon scanning, have revealed hidden cavities, including a large void above the Grand Gallery. It remains one of the greatest symbols of ancient Egypt and a testament to human achievement.
