Nagshe-e Jahan Square.
Isfahan. Iran.
The entry gateway, like those of the Grand Bazaar and the Masjed-e Shah, was a recessed half-moon. Also, like in the Masjed-e Shah, the lower facade of the mosque and the gateway are constructed of marble, while the haft-rangi tiles (هفترنگی, lit. "seven-coloured", "polychrome mosaics") decorate the upper parts of the structure.[7] Creation of the calligraphy and tiles, which exceed, in both beauty and quality, anything created beforehand in the Islamic world, was overseen by Master calligrapher Ali Reza Abbasi.
