The smoke of “Red Castle” blackened Delhi!

Quoted by ISNA; A study on the Red Castle, published in June in the journal of free and judged Heritage, was conducted between the ages of 1 and 2 by researchers in India and Italy.

Experts have found that these black shells, or in fact sediments formed due to chemical interactions between the pollutants and walls of the Red Sand Castle, are between 1.5 mm and 2.5 mm thick and can damage the complex engravings if not protected.

The formation of black layers on the upper and lower windows of the castle has been observed. Delhi, one of the most polluted cities in the world, is often the headline of the news, especially in the winter months.

Environmentalists have repeatedly warned of the destructive effect of contamination on heritage structures in the capital and several other states.

According to the BBC, the Supreme Court announced that the Taj Mahal, the famous 17th -century tomb made of white marble, was green and brownish, and called on the Uttar Pradesh state to take steps to preserve it.
