The Letter of Aurangzeb
This is supposed to be a copy of the original letter from Aurangzeb himself written in 1652, complaining of the extensive repairs that are in need of being done on the Taj Mahal. He says that several rooms on the second storey, the secret rooms and tops of the seven storey ceilings have all absorbed water through seepage and are so old that they were all leaking, and the dome had developed a crack on the northern side. This was in spite of the fact that the rumor is that the Taj was finished being built in 1653. The logic of this is that Mumtaz was supposed to have died around 1631, and it is said that it took 22 years to build the Taj. However, in the letter herein Aurangzeb ordered immediate repairs at his expense while recommending to the emperor that more elaborate repairs such as the roof be opened up and redone with mortar, bricks and stone.
Aurangzeb's letter is recorded in at least three chronicles titled 'Aadaab-e-alamgiri ', 'Yaadgaarnama 'and the ' Muraaqqa-I-Akbarabadi ' (edited by Said Ahmad, Agra, 1931, page 43, footnotes 2).
In any case, if the Taj was a new building, there would no doub not be any need for such extensive repairs.
