The Pyramids of Giza are located on the Giza Plateau, near Cairo, Egypt, and include three main pyramids: the Great Pyramid of Khufu, the Pyramid of Khafre, and the Pyramid of Menkaure.
The Great Pyramid of Khufu, also known as the Pyramid of Cheops, is the largest and oldest of the three, standing at an original height of 146.6 meters (481 feet).
They were built during the Fourth Dynasty of the Old Kingdom of Egypt, around 2580-2560 BC.
The Great Pyramid was the tallest man-made structure in the world for over 3,800 years until the completion of the Lincoln Cathedral in England in 1311 AD.
The Pyramids of Giza were constructed using limestone and granite, with an estimated 2.3 million blocks used for the Great Pyramid alone.
Each block of the Great Pyramid weighs an average of 2.5 tons, with some blocks weighing up to 80 tons.
The precise methods used to construct the pyramids remain a mystery, with theories ranging from ramps to levers and sledges.
The Great Pyramid is aligned with incredible precision to the cardinal points of the compass, demonstrating the advanced understanding of astronomy and engineering by the ancient Egyptians.
The Pyramid of Khafre, the second-largest pyramid, is often mistaken for the largest due to its higher elevation and the intact limestone casing at its peak.
The Pyramid of Menkaure is the smallest of the three main pyramids, standing at 65 meters (213 feet) tall.
The Sphinx, a colossal limestone statue with the body of a lion and the head of a pharaoh, is located near the pyramids and is believed to represent Pharaoh Khafre.
The pyramids were originally covered in smooth Tura limestone casing stones, which reflected the sun's light and made the structures shine brilliantly.
The Giza complex includes several smaller pyramids, known as queens' pyramids, as well as mortuary temples and causeways connecting them to the Nile River.
The Pyramids of Giza have been a source of fascination and study for centuries, inspiring countless theories, legends, and scientific investigations.
The site has been designated a UNESCO World Heritage Site since 1979, recognizing its cultural and historical significance as one of the Seven Wonders of the Ancient World.
