The document provides an overview of prehistoric and ancient Egyptian architecture. In prehistory, humans first lived in caves for shelter and protection. They later developed more structured huts and shelters using branches, animal skins, and stones. During the Stone Age, humans constructed stone structures like menhirs, dolmens, and Stonehenge. In ancient Egypt, the geography and annual flooding of the Nile river was important to architecture. Egyptians built structures like dams, houses made of mudbricks, and mastabas for burial. Mastabas evolved into stepped and smooth-sided pyramids built by pharaohs like Djoser, Sneferu, and others as expressions of power and for burial purposes
