Shah Mosque in Isfahan is located on the southern side of Naqsh-e-Jahan Square or Imam Square as it is also known. The construction of Shah mosque began in 1611 during the Safavids period and was officially opened in 1629. The entrance to the mosque is 27 meters high and crowned with two minarets standing at 42 meters. The Iwan (a rectangular hall or space, usually vaulted, walled on three sides, with one end entirely open. I had to look this up when I was there I had no idea what it was) that opens to the Qibla(the direction you face for prayer) is 33 meters high. Behind that is the dome it is the largest in the city and it stands 52 meters high. They say the beauty and splendour of this dome is largely due to its seven colour mosaic tiles and calligraphic inscriptions.
One thing that I found particularly amazing was the way the dome was acoustically engineered. There is a small square directly under the pinnacle of the dome. When you stand on this square and talk there is an echo that will echo several times. If you step more than 30 centimetres off the square there is no more echo. I was pretty amused by this maybe annoyingly so for some others.
Apparently the dome is symmetrically and mathematically perfect. Meaning that every opposing point was identical. I had no real way of proving this one way or the other but it was crazy to think about considering the size.
Personally I could not comprehend what was going on with the construction. The precision and perfection of such complicated shapes and the sheer magnitude had me mind blown. That is before you even take into account the colours, paintwork and the amount of tiles that have gone into it.
The square in the centre of the floor is the square you stand on for the acoustics.
Unfortunately there was something being constructed around the entrance for an upcoming festival so I could not get a perfect view but once inside I was in awe.
