The reign of Shah Jahan in the Mughal period is called the Golden Age. Shah Jahan built the gold Takht-e-Taus (Peacock Throne) with jewels worth crores of rupees including the Kohinoor. In 1739, Nadirshah was looted from Delhi's Red Fort. Shah Jahan also built the urn on the dome of the Taj with gold. 466 kg of gold was used in it. In 1810, the British officer Joseph Taylor got it removed and got a gold polished copper urn. This urn has been replaced three times so far. If India had not been robbed of gold birds in history, today's India would have been rich. Historian Rajkishore Raje in his book 'Tawarikh-e-Agra' has made full mention of changing the Kalash of Taj Mahal thrice. Raje writes that the urn of the Taj Mahal was made of 40 thousand weights (466 kg) of gold. This gold was given from the royal treasury. The urn was prepared under the supervision of Kazim Khan, called from Lahore. The Moon and Kalash are made on top of it. This urn of gold was taken off by British officer Joseph Taylor in the year 1810. It was replaced by an urn made of gold polished copper. This urn was subsequently replaced in the year 1876 and 1940. The shape of the Kalash of the Taj Mahal on the jasmine floor in front of the guest house was made by Nathuram in 1888 on the directions of the British archaeologists. It was built so that there is no problem in the future of the urn. The height of the present-day Kalash at the dome of the Taj Mahal is 9.29 meters. D. Dayalan has given this information in his book 'Taj Mahal and Its Conservation'.
