Giza Necropolis (also called the Giza pyramid complex) is on the Giza Plateau near the city of Cairo, Egypt. It is about 8 kilometres (5 mi) inland into the desert from the ancient town of Giza on the Nile, and about 25 kilometres (15 mi) southwest of Cairo city centre. The Great Pyramid is the only remaining monument of the Seven Wonders of the World. Construction is thought to have taken 20,000 workers and 20 years.
