Restoration or Intervention(Approaches the type of intervention in historical contexts of cities)

History of skeletal interventions, optimization and urban repair is as long as urbanisms history. Considering physical elements of urban textures constitute housing and connecting networks, and these elements have limited life, and cities have been subject to various destructing factors over the time, thus urban textures decades need restoration and renovation whether due to gradual exhaustion resulting from weather and natural factors such as earthquake, flood, avuncular, or resulting from human factors such as wars and arbitrary interventions resulting from will or governors or even residents. Thus, always resulting from various factors, the city has always repaired itself as a living organism. Renovation and reconstruction of urban textures have a long history, but history of attention to old textures in its today concept and developing various organizations and regulations for renovation and restoration of the buildings in old and worn-out textures, which have been constructed without observing urbanism principles and regulations, dates back to second half of 18th century. First steps in this regard were taken by Western Europe especially England and France.The way of intervention and dealing with old texture in different counties varies considering governing political, economic, and social conditions. However, they are yet common in some principles and methods. The aim of providing this discussion is achieving common principles between countries, in one hand, and investigating experiences in relation with organizing and restoring old textures and obtaining more comprehensive and perfect attitude, on the other hand
