During the Stone Age, from ~10,000 BCE until ~800 BCE, permanent dwellings and settlements were established. These Neolithic building types were made with locally sourced materials and mimicked naturally formed landscapes. The construction methods used were simple and primitive to support nomadic lifestyles. This era also saw the introduction of non-residential building types such as funerary buildings, religious buildings, and ritual/ceremonious buildings.
