The famous structure in Egypt known as a tomb is the Great Pyramid of Giza. It is the largest of the three pyramids on the Giza Plateau and was built as a tomb for the Pharaoh Khufu around 2580–2560 BC. The Great Pyramid is a remarkable example of ancient engineering and has fascinated historians and archaeologists for centuries. Originally covered in smooth, white Tura limestone, the pyramid was part of a complex featuring temples and smaller pyramids for queens. Today, it stands as a testament to the architectural and cultural achievements of ancient Egypt and is a UNESCO World Heritage Site.
