Rajasthan's beautiful Pink City Jaipur, was the stronghold of a clan of rulers whose three hill forts and series of palaces in the city areimportant attractions. Known as the Pink City because of the colour of the stone used exclusively in the walled city, Jaipur's bazaars sell embroidered leather shoes, blue pottery, tie and dye scarves and other exotic wares. Western Rajasthan itself forms a convenient circuit, in the heart of the Thar desert which has shaped its history, lifestyles and architecture. Jaipur has been laid according to the conventional nine-grid pattern that astrologers believe to be lucky, and which has been recommended in the ancient Indian treatise on architecture. Each grid consists of a square, and these have been planned so that, at the heart of the city is the City Palace.
