The Mughal monument has four free-standing minarets that frame the tomb. Each minaret is more than 130 ft tall, and divided into three equal parts by two working balconies.
"ASI is involved in conservation work from time to time. Right now, our chemical wing is working on the conservation of North-West minaret. Next is South-East minaret on which folding is there, and its white marbles and black marble borders will be changed. Besides these, some circular steps will also be changed," an ASI official told PTI.
Elaborating on the nature of conservation work carried out at the monument, he said, "Conservation work is of many types. If the structure is of red sandstone, then we use the same for restoration. If it involves marble, there are other types-simple or engraving work which includes yellow, white and black marble."
ASI officials inspect the structure on a routine basis. Whenever there is a need, a proposal is submitted to the headquarters, and accordingly the funds are made available, he said.
