() You might assume the world's biggest pyramid is in Egypt. Good idea, but wrong guess! The Great Pyramid of Cholula in the State of Puebla in Mexico is the largest pyramid, and the largest monument ever constructed. It is 54 m (177 ft) tall, and its base covers an area of nearly 18.2 ha (45 acres). Its total volume has been estimated at 3.3 million m³ (166,538,400 ft³) compared with the current volume of 2.4 million m³ (84,755,200 ft³) for the Pyramid of Khufu in Egypt.
Also known as Tlachihualtepetl (Nahuatl for "artificial mountain"), the temple may have been dedicated to the god Quetzalcoatl. The architectural style of the building was closely linked to that of Teotihuacan in the Valley of Mexico, although influence from the Gulf Coast is also evident, especially from El Tajín.
The Egyptian pyramids, however, are 138 pyramids in total. Most of them were built as tombs for the country's Pharaohs and their consorts during the Old and Middle Kingdom periods. 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 measures 138.8 metres (455 ft) and it was the tallest man-made structure in the world for over 3,800 years.
