Holy Basin (Hebrew: האגן הקדוש, HaAgan HaKadosh), or Historic Basin (Hebrew: האגן ההיסטורי, HaAgan HaHistori) is a modern Israeli term for a geographical area in Jerusalem that includes the Old City and its adjacent territories. The term was coined by the contemporary Israeli generation as part of a political-academic discourse on how one refers to the area in Jerusalem where the historical and holy sites are concentrated.[1][2] The term is being used in the field of geographical research and in contemporary geo-political studies specializing in urban planning, such as local master plans for Jerusalem and studies concerning the political future of the city.
