The Egyptian pyramids are ancient pyramid-shaped, masonry structures located in Egypt.
138 pyramids have been discovered in Egypt as of 2008; the last pyramid was built in 1570 BC. Most were built as tombs for the country's Pharaohs and their consorts during the Old and Middle Kingdom periods. The earliest known Egyptian pyramids are found at Saqqara, northwest of Memphis. The earliest among these is the Pyramid of Djoser (constructed 2630 BCE–2611 BCE) which was built during the third dynasty. This pyramid and its surrounding complex were designed by the architect Imhotep, and are generally considered to be the world's oldest monumental structures constructed of dressed masonry.
The most famous Egyptian pyramids are those found at Giza, on the outskirts of Cairo. Several of the Giza pyramids are counted among the largest structures ever built.
The Pyramid of Khufu at Giza is the largest Egyptian pyramid. It is the only one of the Seven Wonders of the Ancient World still in existence. It took atleast 4,000 crafts men and a thousand of labourers to build a pyramid.
