The Taj Mahal is slowing changing colour due to pollution and insect dung.
The famous tomb, built in the 17th Century from white marble and other materials, had turned yellow and was now turning brown and green.
The government has previously shut thousands of factories near the Taj Mahal. However, India’s Supreme Court has just instructed the government to seek foreign help to fix the problem.
Why is India’s Taj Mahal turning green?
Sewage in the Yamuna River, alongside the palace, attracts insects which excrete waste onto the palace’s walls, staining them.
The Taj Mahal was built by the Mughal Emperor Shah Jahan in the city of Agra and is now one of the world’s leading tourist attractions, drawing as many as 70,000 people every day.
