Early men chose locations that could be defended against predators and rivals and that were shielded from inclement weather. Many such locations could be found near rivers, lakes, and streams, perhaps with low hilltops nearby that could serve as refuges. Since water can erode and change landscapes quite drastically, many of these campsites have been destroyed. Our understanding of Paleolithic dwellings is therefore limited.
As early as 380,000 BC, humans were constructing temporary wood huts . Other types of houses existed; these were more frequently campsites in caves or in the open air with little in the way of formal structure. The oldest examples are shelters within caves, followed by houses of wood, straw, and rock; a few examples exist of houses built out of bones.
Caves are the most famous example of Paleolithic shelters, though the number of caves used by Paleolithic people is drastically small relative to the number of hominids thought to have lived on Earth at the time. Most hominids probably never entered a cave, much less lived in one. Nonetheless, the remains of hominid settlements show interesting patterns. In one cave, a tribe of Homo neanderthalensis kept a hearth fire burning for a thousand years, leaving behind an accumulation of coals and ash. In another cave, post holes in the dirt floor reveal that the residents built some sort of shelter or enclosure with a roof to protect themselves from water dripping on them from the cave ceiling. They often used the rear portions of the cave as middens, depositing their garbage there.
In the Upper Paleolithic (the latest part of the Paleolithic), caves ceased to act as houses. Instead, they likely became places for early people to gather for ritual and religious purposes.
Tents and Huts
Modern archaeologists know of few types of shelter used by ancient peoples other than caves. Some examples do exist, but they are quite rare. In Siberia, a group of Russian scientists uncovered a house or tent with a frame constructed of mammoth bones. The great tusks supported the roof, while the skulls and thighbones formed the walls of the tent. Several families could live inside, where three small hearths, little more than rings of stones, kept people warm during the winter. Around 50,000 years ago, a group of Paleolithic Homo sapiens camped on a lakeshore in southern France. At Terra Amata, these hunter-gatherers built a long and narrow house. The foundation was a ring of stones, with a flat threshold stone for a door at either end. Vertical posts down the middle of the house supported roofs and walls of sticks and twigs, probably covered over with a layer of straw. A hearth outside served as the kitchen, while a smaller hearth inside kept people warm. Their residents could easily abandon both dwellings. This is why they are not considered true houses, which was a development of the Neolithic period rather than the Paleolithic period.
