The greatest roofed bazaar of the world, and enjoying a history of nine centuries, the ancient Tabriz Historic Bazaar Complex continues to function as a prominent trade center. Previously, the Complex used to manifest as a main trade center on the Silk Road, and an important place for cultural exchanges, too. Architecturally, the Tabriz Historic Bazaar Complex comprises a mixture of mud-brick structures, roofed bazaars, and closed spaces classifiable for various categories of activities. The complex constitutes a complete sample of the Iranian traditional trade and cultural systems.
