Taj Mahal vs Inco Superstack

Informations

The Taj Mahal (; lit. 'Crown of the Palace', [ta?d? ?m???(?)l]) is an ivory-white marble mausoleum on the southern bank of the river Yamuna in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor Shah Jahan (reigned from 1628 to 1658) to house the tomb of his favourite wife, Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. The grave is the centrepiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall. Building of the mausoleum was basically completed in 1643, but work continued on other stages of the job for the following 10 years. The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be approximately 32 million rupees, which in 2020 will be approximately 70 billion rupees (about U.

S. $916 million). The construction project employed some 20,000 artisans under the guidance of a board of architects led by the court architect to the emperor, Ustad Ahmad Lahauri. The Taj Mahal was designated as a UNESCO World Heritage Site in 1983 for being'the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage'. It is viewed by many as the best example of Mughal architecture and a symbol of India's rich history. The Taj Mahal attracts 7--8 million visitors annually and in 2007, it had been announced a winner of the New 7 Wonders of the World (2000--2007) initiative.

The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the 2nd tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It's also the second tallest freestanding structure of any kind in Canada, behind the CN Tower but forward of First Canadian Place. It's the 40th tallest freestanding structure in the world. The Superstack is situated on top of the biggest nickel smelting operation in the world at Vale's Copper Cliff processing centre in the city of Greater Sudbury. In 2018, Vale declared that the stack will be decommissioned and dismantled beginning in 2020. On July 28, 2020, Vale declared that the stack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in case of a malfunction in the new system, after which the dismantling of this Superstack will begin. In addition to further reducing sulfur dioxide emissions by 85 percent, the decommissioning of the pile is expected to cut the complex's natural gas consumption in half.
