This document provides an overview of prehistoric architecture from the early migration of humans out of Africa to the Neolithic period. It discusses early human shelters like those found in caves and the development of more permanent structures during the New Stone Age as people transitioned to farming and animal domestication. Notable examples of prehistoric architecture mentioned include Stonehenge, the megalithic temples of Malta, and the large Neolithic settlement of Catal Huyuk in Turkey. Building materials progressed from plant and animal materials in early shelters to stone, adobe, and polished stone tools in the New Stone Age, along with advances in construction techniques.
