who built the jantar mantar why was it build
Jantar Mantar, New Delhi Jantar Mantar is located in the modern city of New Delhi. It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 onwards, as he was given by Mughal emperor Muhammad Shah the task of revising the calendar and astronomical tables. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710. Later research, though, suggests 1724 as the actual year of construction.
Tadeusz Kościuszko Kościuszko was born in February 1746, in a manor house on the Mereczowszczyzna estate in Nowogródek Voivodeship, Grand Duchy of Lithuania, a part of the Polish–Lithuanian Commonwealth. His exact birthdate is unknown. At age 20, he graduated from the Corps of Cadets in Warsaw, Poland, but after the outbreak of a civil war involving the Bar Confederation in 1768, Kościuszko moved to France in 1769 to pursue further studies. He returned to Poland in 1774, two years after its First Partition, and took a position as tutor in Józef Sylwester Sosnowski's household. After Kościuszko attempted to elope with his employer's daughter and was severely beaten by the father's retainers, he returned to France. In 1776, Kościuszko moved to North America, where he took part in the American Revolutionary War as a colonel in the Continental Army. An accomplished military architect, he designed and oversaw the construction of state-of-the-art fortifications, including those at West Point, New York. In 1783, in recognition of his services, the Continental Congress promoted him to brigadier general.
