“Slumdog Millionaire” (2008, eight Oscars) was shot in the streets of Mumbai; the Taj Mahal remains the jewel of Mughal architecture.
The Taj Mahal's marble seems to shift hue with the light: pinkish at dawn, white by day, golden under the moon.
Visit the Taj Mahal at dawn to beat the crowds. An eSIM is invaluable: the IRCTC train app, Ola or Uber, Google Translate, and price-checking.
