Imam Mosque, Iran

   Headlining beside one of the world's largest squares, Esfahan's Imam Mosque is a tiled wonder. Completely covered, inside and out, with pale blue and yellow ceramic tiles, it's a stunning 17th-century mosque, with its tiles seeming to change colour depending on the light conditions. The main dome is 54 meters high and intricately patterned in a stylized floral mosaic, while the magnificent 30 meter high portal is a supreme example of architectural styles from the Safavid period (1502 - 1772). The mosque sits askew to the square, at about 45 degrees, so that it faces Mecca.

  Imam Mosque stands in south side of Naghsh-i Jahan Square. Built during the Safavid period, it is an excellent example of historic Islamic architecture of Iran, and regarded as one of the masterpieces of Persian Architecture. The Shah Mosque of Esfahan is one of the everlasting masterpieces of architecture in Iran. It is registered, along with the Naghsh-i Jahan Square, as a UNESCO World Heritage Site. Its construction began in 1611, and its splendor is mainly due to the beauty of its seven-colour mosaic tiles and calligraphic inscriptions.The mosque is one of the treasures featured on Around the World in 80 Treasures presented by the architecture historian Dan Cruickshank.
