This paper deals with the control of spaces by the regulations in a Zone of Protected Architectural and Urban Heritage (ZPPAUP), which was enacted in 1983 to protect the historical landscape. In the regulation of protecting landscape, all elements forming old quarters are classified into 41 categories, and examined in view of two aspects; namely, the historical and cultural value of the space itself, and those values of the entire urban space. Then problems concerning the urban heritage are indicated on two maps using a legend in order to arrange the landscape. Then the facade of each building must be repaired in accordance with the traditional style, so as to protect the urban structure.
