Pyramid of Giza
The oldest of the Seven Wonders of the World, the Pyramids of Giza are an icon of Egypt. Standing at a height of 146.5 metres, the Giza Pyramid held the title of tallest man-made structure in the world for over 3,800 years. The pyramids were erected on the west bank of the Nile, around 2580–2560 BC. Soaring above the city of Cairo, the pyramids are visible from most parts of the city. The pyramids were constructed using solid blocks of granite, mortar and limestone.
