Courtyards in the historic cores of Barcelona and Kermanshah are composed. They are put together, and connected to, a larger urban sequence of open spaces and pedestrian circulation layouts. In spite of the scant bibliography, all throughout the Mediterranean coastline Persian precedentis still found today on open space form. Persians used rural and urban plots of land to organize cities. As Aristotle recorded in his urban theories, Persian know how was inherited in Ancient Greek town planning, namely through cadastral alignment surveys and a complex tax system dividing private and public property. In Barcelona and Kermanshah ancient property lines sti ll define today urban space, streets and courtyards, leading to old markets. Space flows to newer parts of the city through historical,agriculturally used plots of land. O pen spaces at the outskirts , where the public space of old fortifications walls turned into private housing lots, has also changed and affected by new infrastructure. An urban process similar to what is happening today at the outskirts of Kermanshah. The post occupancy evaluation study presented in this paper aims at showing how of the courtyard designed by Enric Miralles advanced composite theories of urban form and the space syntax precepts that consider precedent. Concepts of social Integration of children and connectivity prove useful only when they are considered at the programming, early stages of the design process only with accurate historic mapping sources.
