Madurai in 3 days: one of the oldest continuously inhabited cities in the world (2,500+ years), where the Meenakshi Temple receives 20,000 devotees daily and employs 1,000 priests, where Gandhi wore a dhoti for the first time in 1921 after seeing the poverty of Madurai's people, where Tamil is the world's oldest living literary language, and where the jasmine flowers sold in the temple market weigh 4 tonnes per day.
