"The largest pyramid in Egypt is the Great Pyramid of Giza. The pharaoh Khufu, who ruled during the Old Kingdom's Fourth Dynasty, was buried there. The pyramid is the oldest of the Seven Wonders of the Ancient World and the only one that has mostly survived. It was constructed in 2600 BC over a span of roughly 26 years. It is the most well-known structure inside the Giza pyramid complex, which is a part of the ""Memphis and its Necropolis"" UNESCO World Heritage Site. In relation to the three great pyramids of Giza, it is located near the northeastern end. For over 3,800 years, the Great Pyramid was the tallest man-made edifice in the world, standing at an initial height of 146.6 meters (481 feet). The pyramid's height was reduced to its current 138.5 meters (454.4 feet) when the smooth white limestone casing was mostly eroded over time; the underlying core structure is what is visible now. Including an interior hillock, the base's dimensions were around 230.3 meters (755.6 feet) square, resulting in a volume of about 2.6 million cubic meters (92 million cubic feet). An estimated 2.3 million massive blocks, totaling 6 million tonnes in weight, were quarried in order to build the Great Pyramid. Most of the stones are only loosely prepared and vary greatly in size and shape.Mortar was used to join the outer layers. It was built primarily of native limestone from the Giza Plateau. Additional blocks, including blocks of granite weighing up to 80 tons for the ""King's Chamber"" construction and white limestone from Tura for the casing, were brought in by boat on the Nile. The Great Pyramid is known to contain three rooms. The lowest, which was left incomplete, was carved into the bedrock that the pyramid was constructed on. Above ground, inside the pyramid structure, are the so-called Queen's Chamber and King's Chamber, which house a granite sarcophagus. His vizier, Hemiunu, is credited by some as the Great Pyramid's architect. The precise construction methods are the subject of numerous competing scientific and alternative theories, but as with most constructions of this type, there is no clear consensus. Five buried solar barques, two mortuary temples (one near the pyramid and one near the Nile) connected by a causeway, tombs for Khufu's immediate family and court, including three smaller pyramids for Khufu's wives, and an even smaller ""satellite pyramid"" made up the funerary complex surrounding the pyramid.

Johannesburg is a city in South Africa's Gauteng province. It is the main financial and industrial center of the nation. Johannesburg, one of the newest big cities in the world, was established in 1886 after gold was discovered. Prior to becoming one of South Africa's four provinces, the city was a part of the Transvaal, an independent Afrikaner, or Boer, republic. Today, the city is a part of one of South Africa's nine provinces, Gauteng, which means "Place of Gold" in Sotho. The Highveld, a wide, grassy plateau that stretches across the interior of South Africa, is where Johannesburg is located. The city is situated on the edge of the Witwatersrand, also known as the Rand, which is a chain of low, rocky ridges that serves as a watershed between the drainages into the Atlantic and Indian seas. The city is between 5,700 and 5,930 feet (1,740 and 1,810 meters) above sea level. The climate of Johannesburg is moderate. The average temperature is around 75 °F (24 °C) in the summer and 55 °F (13 °C) in the winter, with very few periods below freezing. In both winter and summer, the city receives roughly eight hours of sunlight each day. Although the overall amount of rainfall fluctuates greatly from year to year, it averages around 28 inches (700 millimeters) annually. A major location for several creative and cultural industries, Johannesburg is a cultural center in South Africa with a diverse range of cultural venues. In addition to a plethora of other museums, theaters, galleries, and libraries, Johannesburg is home to the South African Ballet Theatre, the National School of Arts, and the University of Witwatersrand's School of the Arts.The Central Business District of Johannesburg is home to the Johannesburg City Library. The city is home to a number of Premiership and National First Division football teams. The top Johannesburg teams in the Premiership, such as Orlando Pirates (also known as the Buccaneers) and Kaizer Chiefs (also known as Amakhosi), are bitter rivals. They are headquartered at the Orlando and FNB stadiums in the city. Soccer City, the site of the 2010 FIFA World Cup final, hosts a number of major league and cup matches. FC AK and Jomo Cosmos are the teams in the First Division. The stadiums used by Katlehong City and Alexandra United are Alexandra and Reiger Park, respectively.
