It was a wonderful piece of Mogul aristry and workmanship ever created, unsurpassed in beauty and skill. The cost, it is believed, could have been twice that of the cost of building the Taj by Shah Jehan'  With great fanfare the inagural ceremony was held on March 22, 1635 an auspicious day coinciding with Eid-al-Fitr, the end of Ramdan.
