Taj Mahal significant event construction
Construction
The Taj Mahal is built on a parcel of land to the south of the walled city of Agra. Shah Jahan presented Maharaja Jai Singh I with a large palace in the centre of Agra in exchange for the land. An area of roughly 1.2 hectares (3 acres) was excavated, filled with dirt to reduce seepage, and levelled at 50 metres (160 ft) above the riverbank level. In the tomb area, piles were dug and filled with stone and rubble to form the footings of the tomb. Instead of lashed bamboo, workmen constructed a colossal brick scaffold that mirrored the tomb. The scaffold was so enormous that foremen expected it to take years to dismantle.The Taj Mahal was constructed using materials from all over India and Asia. It is believed over 1,000 elephants were used to transport building materials. Some 22,000 labourers, painters, embroidery artists and stonecutters were used. The translucent white marble was brought from Makrana, Rajasthan, the jasper from the Punjab region, jade and crystal from China. The turquoise was from Tibet and the Lapis lazuli from Afghanistan, while the sapphire came from Sri Lanka and the carnelian from Arabia. In all, 28 types of precious and semi-precious stone were inlaid into the white marble.According to the legend, Shah Jahan decreed that anyone could keep the bricks taken from the scaffold, and thus it was dismantled by peasants overnight. A 15-kilometre (9.3 mi) tamped-earth ramp was built to transport marble and materials to the construction site and teams of 20 or 30 oxen pulled the blocks on specially constructed wagons. An elaborate post-and-beam pulley system was used to raise the blocks into the desired position. Water was drawn from the river by a series of purs, an animal-powered rope and bucket mechanism, into a large storage tank and raised to a large distribution tank. It was passed into three subsidiary tanks, from which it was piped to the complex.The plinth and tomb took some 12 years to complete. The remaining parts of the complex took an additional 10 years and were completed in order of minarets, mosque and jawab, and gateway. Since the complex was built in stages, discrepancies exist in completion dates due to differing opinions on "completion". Construction of the mausoleum itself was essentially completed by 1643 while work on the outlying buildings continued for years. Estimates of the cost of construction vary due to difficulties in estimating costs across time. The total cost at the time has been estimated to be about ₹ 32 million, which is around ₹ 52.8 billion ($827 million US) based on 2015 values.
