Assuming that, in this particular type of human settlements, heritage buildings such as the cathedral, the town hall, and other similar constructions operate as tourist attractors, this research investigates to what extent the location of these buildings, together with the two main syntactic properties of the elements of the street network—integration and choice—can describe the spatial distribution of economic activities in touristic heritage cities, using the UNESCO Heritage site of Toledo, Spain, as case study. In order to investigate this question, each segment of the street network has been characterized with four main values: (1) economic activity, (2) spatial integration, (3) spatial choice, and (4) heritage intensity. The first value, economic activity, represents the presence or absence of economic activity in the buildings that are accessible through each corresponding street segment. The second value, spatial integration, accounts for the integration values that each segment has at two different scales—the neighborhood and the whole city. The third value, spatial choice, considers the choice values that each segment has, again, at these two scales. The fourth value, heritage intensity, reflects the proximity of listed building to each individual street segment. Street audits were used to record the economic activities taking place in the ground floors and upper floors of the buildings within the historic city. Space Syntax analysis was used to determine the different integration and choice values for each street segment; and GIS tools were used to establish their heritage intensity. Afterwards, statistical analysis was employed to investigate the relationships among these four variables, showing how the distribution of economic activity in the street network of the historic city of Toledo can be well explained by the other three variables—spatial integration, spatial choice and heritage intensity.References Ashworth, G.J., Tunbridge, J.E.
