Shah Mosque, also known as Imam Mosque, is a masterpiece of Persian architecture located in Isfahan, Iran. It stands at the southern end of Naghsh-e Jahan Square, constructed during the Safavid dynasty under the order of Shah Abbas I of Persia. Built between 1611 and 1629, the mosque is an excellent example of Islamic architecture of Iran and regarded as one of the masterpieces of Persian Architecture. It features a magnificent portal entrance that is over 30 meters high, decorated with splendid tile work, primarily in blue color themes, which has become a signature element of the mosque. The mosque's architectural innovation, as seen in the seven-color mosaic tiles and calligraphic inscriptions, contributes to its grandeur. It contains four iwans and a large central dome flanked by two towering minarets. The acoustic properties and reflections in the central dome chamber have attracted several researchers and tourists. The mosque is also part of the UNESCO World Heritage Site which includes the Naghsh-e Jahan Square.
