The multiple layer historical city is a living and functioning city, as any other - it is inhabited by people, different activities take place in it, and it must answer to various needs, according to its general definition as a city. But it has a distinctive dimension - the dimension of depth-, in more than one sense: contents and values derived from its history, and physical multi-layered depth, where its hidden roots are contained. The character of this city is derived from that depth. Its physical layout is loaded with memories of urban structures buried beneath it, and their marks are revealed, in various ways, above the ground.
The aim of this research is to analyze and establish the methods of learning and principles for the design and development of a multiple layer historical city, according to its special nature. The city of Acco was chosen as a case of study.
The importance of learning and establishing guidelines for approaching the future development of the multiple layer historical city increases with the understanding that such cities will probably not be created in the future, and therefore their number is limited. So, such cities are to be conserved as a testimony of urban-historical processes which have passed from the world. This thesis' basic assumption is, that further stages in the design and planning of the multiple layer historical city should be based on an ideology of connecting to the past.
For that purpose a deep theoretical survey and discussion of four basic issues is done: the multiple layer historical city and its particular nature; the history of the city and its role in the city systems; the city and its components, and finally, the issue of conservation.
Based on that discussion, conclusions for learning and designing the multiple layer historical city are formulated. The special learning stages required for such a city are described. Design principles, both on the ideological and physical levels are, as well, established.
Finally, the learning methods and the design principles for the multiple layer historical city suggested in this work, are demonstrated in the design of the city of Acco. Guidelines for the design of Acco are presented, starting with the whole town, through the old city and ending with a detailed description of part of it.
These design guidelines demonstrate how historical and multiple layer components can and should be combined in the urban system, as integral part of its planning, and by this to contribute to an enrichment of its contents.
