The concept of Al Noor mosque in the city of Dammam aimed to create a dynamic movement of the worshiper’s journey as the journey begins by descending a slope from zero level to -4m level, where the entrance of the prayer hall is. After entering the hall, the ceiling level rises gradually until it reaches the mihrab in order to achieve the excpireince of opennes of vision and exit from a narrow area to an open area which represents relief after narrowness.
