Jaipur was founded on 18 November 1727 by Maharaja Sawai Jai Singh II, the ruler of Amber, after whom the city has been named. 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 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 the sprawling Hawa Mahal palace complex, formal gardens, and a small lake. Jaipur is known as the Pink City of India. Hawa Mahal ("Palace of Winds or Palace of the Breeze), was built in 1799 by Maharaja Sawai Pratap Singh, and designed by Lal Chand Ustad in the form of the crown of Krishna, the Hindu god. Its unique five-storey exterior is also akin to the honeycomb of the beehive with its 953 small windows called jharokhas that are decorated with intricate latticework. The original intention of the lattice was to allow royal ladies to observe everyday life in the street below without being seen, since they had to observe strict "purdah" (face cover). The cancellation depicts Hawamahal.
