Jaipur also makes claim to the title of the oldest surviving planned urban center in northern India. Maharaja Sawai Jai (Victory) Singh II who named the new city after himself, employed a scholar to design it as conceived in Shipla Shastra, the ancient Hindu architectural treatise. The grid consisted of seven blocks of white buildings separated by tree-lined wide boulevards. It was a walled city with seven gates. Arched shop-fronts added the Mughal architectural influence.
