The Imam Mosque is one of the most stunning mosques in the world. The wealth of its blue-tiled mosaic designs and its flawlessly balanced Safavid-era structural design form a visually dazzling monument to the imagination of Shah Abbas I and the capacity of his architect. The extravagant decoration of the mosque completely harmonizes the architectural grace.

Work started on the superb entry gateway in 1611, even though it took four years to complete - look for mismatches in its obvious symmetry, intended to imitate the artist's humbleness in the face of Allah. It was not until 1629, the last year of the control of Shah Abbas, that the high dome, and consequently the mosque, was finished. Little has untouched since.

Even though each of the mosque's parts is a stunning success, it is the harmony of the overall design that leaves an eternal feeling. The original intention of the entrance gateway had more to do with its spot on the plaza than with the mosque's sacred goals. Its purpose was mostly ornamental, providing a counterpoint to the Qeysarieh Portal at the entrance hall to the Bazar-e Bozorg.

The central sanctuary offers magnificent views back to the two turquoise minarets above the entrance gateway. Each is surrounded by projecting terraces and white geometric inscription in which the names of Mohammed and Ali are picked out over and over again. Each is topped by a graceful dome.
