Desert oases are geographical phenomena in the desert that, unlike the desert, have water. Water generates the life of plants and animals, and most often also the life of people. Some oases have been continuously inhabited for thousands of years, and some are uninhabited and have been arranged as natural protected areas. Most oases are located in the Sahara desert where there were rest stops for caravans. Some oases are densely built, where the ruins of thousands of years old architecture, vernacular architecture, and contemporary architecture are present in a wide variety of programs that meet the needs of visitors. The author of this work visited a desert oasis in Saudi Arabia during his participation in The First International Conference on Urban and Architectural Heritage in Islamic Countries (FCUAHIC), Riyadh, Saudi Arabia, 23-28 May 2010, where he presented his work entitled „Vernacular Architecture in Bosnia and Herzegovina“.
