This was represented in the form of (elements, construction system, way of covering, or spatial organization), The nature of functions of the local regional feature ranged between (climatic and environmental/semantic/constructional/decorative), and the location of the impact of local feature (horizontal plans/internal and external facades/constructional system). In light of the contemporary architectural products that reflect the general atmosphere of technological globalization and represent global products within their context, parametric mosques emerged as a building style that adopted the environmental factor as one of the basic principles of their parametric design. From here, the question arose about the extent of the relationship between regionalism and contemporary parametric mosques,so the research problem was represented by (the limited knowledge about local regionalism and its relationship to contemporary parametric mosques). The research objective was to determine the regional specificity with its factors within parametric mosques first, and the ( form, function and location) of its reflection within parametric mosques second. The research reached to the limited impact of the cultural contextual factor on the one hand, while the effects of regionalism continued in its natural context on the other hand, and this appeared in various vocabularies within which the climatic and environmental function was rooted at the expense of other functions.
