Mosul is one of the cities that appeared before Islam. Later on it was reformulated according to the islamic planning principles. It remained a model of an arabic islamic city, till the beginning of the twentieth century, when it had witnessed the construction of a number of wide and straight streets penetrating the urban texture of the traditional city, leading to the destruction of its social and physical structure. Then, break-through streets started to be more convenient strategy adopted by the planning authorities to realize their urgent objectives for raising the quality of life in the traditional city of mosul. After critically reviewing the previous literature, it was concluded that none of those studies have dealt, scientifically and objectively, with the problem of defining the impact of break-through streets upon the spatial organization of Old Mosul. This defect was adopted as the problem of this study aiming at the definition of that impact.
Suitable methodology was adopted to realize the study objectives, using space syntax techniques to analyze and describe the spatial organization of Old Mosul before and after the adoption of break-through streets strategy.
The conclusions provide a more clear description of the spatial organization of the old city of Mosul before and after the penetration of break-through street
