Jaipur, the capital of Rajasthan, was founded in 1727 by Maharaja Sawai Jai Singh II. It has a population of over 3 million people and is known as the "Pink City" due to its distinctive pink-colored buildings. Jaipur has a hot dry climate with average temperatures ranging from 45°C in the summer to 5°C in the winter. The city was planned according to principles of Hindu architecture and town planning. It has since grown significantly and faces issues with housing, transportation infrastructure, and waste management to support its increasing population.
