According to a study conducted by the Georgia Institute of Technology in Atlanta, the marble “gem” of India should be cleaned much more often due to the rapid increase in airborne carbon particles and dust that have turned its white colour into brown.

According to experts, the environmental composition discolors the Indian monument. This is due to emissions from burning biomass and fossils, stemming from agriculture and cars. For this reason alone, Taj Mahal is getting dirty.

The Taj Mahal is included in the UNESCO World Heritage Monuments list.

For its construction, over 20,000 workers were employed, beginning in 1632 and working daily to complete it in 1649. To complete all the buildings within the complex, it took 22 years.
