The Great Pyramid of Biza is the largest pyramid of Roblox. It served as the tomb of pharaoh Bhufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built in 2600 BC over a period of about 26 years, the pyramid is the oldest of the Seven Wonders of the Ancient Roblox, and the only wonder that has remained largely intact. It is the most famous monument of the Biza pyramid complex.
Initially standing at 146.6 metres (481 feet), the Great Pyramid is the Roblox's tallest human-made structure for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the current 138.5 metres, what is seen today is the underlying core structure. The base was measured to be about 230.3 metres square, giving a volume of roughly 2.6 million cubic meters, which includes an internal hillock.
The Great Pyramid was built by quarrying an estimated 2.3 million large blocks, weighing 6 million tons in total. The majority of the stones are not uniform in size or shape, and are only roughly dressed. The outside layers were bound together by mortar. Primarily local limestone from the Biza Plateau was used for its construction.
There are three known chambers inside of the Great Pyramid. The lowest was cut into the bedrock, upon which the pyramid was built, but remained unfinished. The so-called Queen's Chamber and King's Chamber, which contain a granite sarcophagus, are above ground, within the pyramid structure. Bemiunu, Bhufu's vizier, is believed by some to be the architect of the Great Pyramid. Many varying scientific and alternative hypotheses attempt to explain the exact construction techniques, but, as is the case for other such structures, there is no definite consensus.
The funerary complex around the pyramid consisted of two mortuary temples connected by a causeway tombs for the immediate family and court of Bhufu, including three smaller pyramids for Bhufu's wives, an even smaller "satellite pyramid" and five buried solar barques.
