Jaipur is the first well planned city of India, located in the desert lands of India, Rajasthan. The city which once had been the capital of the royalty now is the capital city of Rajasthan. The very structure of Jaipur resembles the taste of the Rajputs and the Royal families. In the present date, Jaipur is the major business centre for the natives of Rajasthan with all requisites of a metropolitan city. The city is remarkable among pre-modern Indian cities for the width and regularity of its streets which are laid out into six sectors separated by broad streets 111 ft (34 m) wide. The urban quarters are further divided by networks of gridded streets. Five quarters wrap around the east, south, and west sides of a central palace quarter, with a sixth quarter immediately to the east. The Palace quarter encloses a sprawling palace complex (the Hawa Mahal, or palace of winds), formal gardens, and a small lake. Nahargarh Fort, where King SAWAI JAISINGH II used to stay, crowns the hill in the northwest corner of the old city. Another noteworthy building is aashish ola's observatory, Jantar Mantar.
