Ancient Egyptian architecture is the architecture of Ancient Egypt, one of the most influential civilizations throughout history, which developed a vast array of diverse structures and great architectural monuments along the Nile, including pyramids and temples.
Due to the scarcity of wood, the two predominant building materials used in ancient Egypt were sun-baked mud brick and stone, mainly limestone, but also sandstone and granite in considerable quantities. From the Old Kingdom onward, stone was generally reserved for tombs and temples, while bricks were used even for royal palaces, fortresses, the walls of temple precincts and towns, and for subsidiary buildings in temple complexes. The core of the pyramids consisted of locally quarried stone, mudbricks, sand or gravel. For the casing stones were used that had to be transported from farther away, predominantly white limestone from Tura and red granite from upper Egypt.
Ancient Egyptian houses were made out of mud collected from the damp banks of the Nile river. It was placed in moulds and left to dry in the hot sun to harden for use in construction. If the bricks were intended to be used in a royal tomb like a pyramid, the exterior bricks would also be finely chiselled and polished.
Many Egyptian towns have disappeared because they were situated near the cultivated area of the Nile Valley and were flooded as the river bed slowly rose during the millennia, or the mud bricks of which they were built were used by peasants as fertilizer. Others are inaccessible, new buildings having been erected on ancient ones. Fortunately, the dry, hot climate of Egypt preserved some mud brick structures. Examples include the village Deir al-Madinah, the Middle Kingdom town at Kahun, and the fortresses at Buhen and Mirgissa. Also, many temples and tombs have survived because they were built on high ground unaffected by the Nile flood and were constructed of stone.
