The Tabriz Historic Bazaar Complex was officially protected in 1975 and has been covered by special stewardship measures until 2010, when it was added to the World Heritage List. The complex covers 27 hectares with over 5.5 kilometres of covered bazaars. Three different protection areas have been established (a nominated area, a buffer zone and a landscape zone), subject to special regulations incorporated into the planning instruments. The management framework is based on the participation of the bazaaris, together with municipal authorities and ICHTOs Tabriz Bazaar Base. Since 2000, numerous complexes within the bazaar have been rehabilitated with the participation of the owners and tenants. Infrastructure has been improved and public facilities have been built.The Tabriz Bazaar is a unique exemple of urban conservation and development project inwhich heritage plays a catalyst role in rejuvenating the tangible and intangible memory of the historic city of Tabriz.
