Hans, their origin, their develop-ment and potential of their structures for future use are treated in this work. Partic-ular focus should be placed on the com-position of the floor plan of this polyfunc-tional building type; where the structure was maintained over centuries, but the function has been permanently modified.
They were in many regions of Anatolia nucleus and starting point of an urban-ization or were inserted in an already existing urban fabric; made possible by the introverted cell structure around the courtyard. In both cases, physical and functional changes can be perceived by the new environment.In today’s context, the fortress-like archi-tecture has become obsolete. As imper-vious blocks they group into commercial zones of Anatolian cities. Hardly used for accommodations anymore, the hans,
due to their floor plan, which is based on a modular system, are redeveloped for goods storage or processing facilities. Furthermore the courtyards are filled with new informal structures.Robert Hillenbrand speaks of hans as miniature cities that were self-sufficient and led to a concentration or zoning of economic activities within the city. Both trends have the common property, that part of the urban area is pulled inwards and confined in a rigid frame. The im-pression of the isolation is enhanced by the surrounding rooms, which act as a thickening of the boundary between the outside and inside of the han. The interac-tion between the han and the urban fabric is blocked.Does this fortified architecture, which has become part of the city and was previous-ly found only extramural, be dismantled and opened to the public?
