This Mosque was completed in 1629, in the last year of the reign of Shah Abbas. Sound bounces back and forth between the floor and ceiling, with the vast dome focusing the sound, forcing it to keep moving back and forth in a regimented fashion. Without a dome, the echo from the ceiling would be lost among all the other sound reflections in the mosque. The iconic blue-tiled mosaic tiles help to provide strong reflections, which is why so many repeats of the echo are heard.
