Later years

In December 1652, Shah Jahan's son Aurangzeb wrote a letter to his father about the tomb, the mosque and the assembly hall of the complex developing extensive leaks during the previous rainy season. In 1658, Shah Jahan was deposed by Aurangzeb and put under house arrest at the nearby Agra Fort from where he could see the Taj Mahal. Upon Shah Jahan's death in 1666, Aurangzeb buried him in the mausoleum next to his wife. In the 18th century, the Jat rulers of Bharatpur attacked the Taj Mahal while invading Agra and took away two chandeliers, one of agate and another of silver, which had hung over the main cenotaph and the gold and silver screen. Kanbo, a Mughal historian, said the gold shield which covered the 4.6-metre-high (15 ft) finial at the top of the main dome was also removed during the Jat despoliation.

By the late 19th century, parts of the buildings had fallen into disrepair. At the end of the century, British viceroy Lord Curzon ordered a restoration project, which was completed in 1908. He also commissioned the large lamp in the interior chamber and replaced the gardens with European-style lawns that are still in place today.

In 1942, the government erected scaffolding to disguise the building in anticipation of air attacks by the Japanese Air Force. Since Indian independence in 1947, the Archaeological Survey of India has been responsible for the maintenance of the monument. During the India-Pakistan wars of 1965 and 1971, scaffolding was again erected to mislead bomber pilots.

In 1983, the Taj Mahal was designated as a UNESCO World Heritage Site for being "the jewel of Islamic art in India and one of the universally admired masterpieces of the world's heritage".

Since the late 20th century, the monument has been affected by environmental pollution which has turned the Taj Mahal yellow-brown. Acid rain and pollution affecting the Yamuna River including the presence of Mathura Oil Refinery, have contributed to the same. After directives by the Supreme Court of India, in 1997 the Indian government set up the "Taj Trapezium Zone (TTZ)", a 10,400-square-kilometre (4,000 sq mi) area around the monument where strict emissions standards are in place.

Concerns for the tomb's structural integrity have recently been raised because of a decline in the groundwater level in the Yamuna river basin, with cracks appearing in parts of the tomb in 2010 and the minarets surrounding the monument showing signs of tilting. Minor damage was reported due to storms on 11 April 2018 and 31 May 2020. In the late 2020s, the Government of India has undertaken various restoration measures, including placing mud packs to restore the white color and replacing broken marble.
