A mountain village in the Caucasus Mountains of Russia, Georgia, Armenia, and Azerbaijan but usually applied to the first two locations.
An aul in Daghestan is a very eerie place. The houses are usually constructed so that their backs form a sort of step to the next row of houses and continue in this way until one reaches the top of the hill or cliff. The roofs form pathways to the neighbors' houses too. The overall effect is that of a sort of pyramidlike shape. The ancient stone towers, old masjids, bazaars, and the strange languages add to the eerieness.
