Back during the Middle Ages when Liwa was ruled by the dessert tribes, one of the most valuable resources to tribes was sources of water. As such, water sources became the cause of conflict, with bandits and rival tribes attempting to gain control over more sources of water. For this reason, it became necessary for most villages and tribes to build fortresses close to the water sources, from within which they could fend off enemy raids. Today, the threats from enemies are, more or less, non-existent. Therefore, the many ancient forts that stand at Liwa have become historic landmarks, which are a symbol of the heritage of the old tribes and villages that inhabited Liwa. Some of the most popular forts in Liwa include the Jabbana Fort, the Qutuf Fort and the Mezzaira'a Fort.
