Всем известно, что в доисторические времена большая часть поверхности суши была покрыта лесами. В местах, где росли деревья, человек использовал дерево для строительства домов себе и своим служащим.
Долговечность дерева и его использования можно наглядно увидеть, например, в таких постройках, как церкви Скандинавии.
В России, где часто достаточно холодно, древесина широко используется как для строительства домов, так и для церквей из-за ее свойства теплоизоляции от холода. Многие старинные русские церкви деревянные, вплоть до куполов, которыми они отделаны.
