Made from mud, dirt, straw and stones, these beehive houses originated around 3700 BC and can be found in rural farming communities, deserts and cities. Each beehive has an oculus hole at the top, which lets in light and sucks out hot air. When there is rain, the conical shape of the beehive keeps the interior dry. They are very cool inside, due to the insulation of the thick walls and are still in use today as residences and storage barns.
