Conservation is defined as activity aimed at ensuring the continued existence of structures that represent the cultural, historic and architectural values within contemporary society alongside recognition of its present and future needs. Why should we conserve these buildings? It seems that Yigal Allon provided a succinct explanation: “A nation that does not respect its past will have a dull present and an uncertain future.” In other words, we need to conserve historic buildings in order to create a sense of historical stability and continuity, as individuals and as a nation. The historic sites are an integral part of the culture; they are built cultural assets. The historic sites that we conserve can be classified according to different criteria.
