Palitana is a city in Bhavnagar district, Gujarat. It is a major pilgrimage centre for Jains. As the temple-city was built to be an abode for the divine, no one is allowed to stay overnight, including the priests. Every Jain believes that a visit to this group of temples is essential as a once in a life time chance to achieve nirvana or salvation.

In 2014, Palitana became the first city in the world to be legally vegetarian. It has outlawed, or made illegal, the buying and selling of meat, fish, and dairy products, and also related jobs or work, such as fishing and penning ‘food animals’.
