Agra, the Taj Mahal
The pollution in Agra is a problem. The city is overcrowded and busy, some days the smog is so dense that you cannot even see the temple from the gateway! This is specially so first thing in the morning. Visitors who expect to see the color of the facade changing with the rise of the sun, may end up disappointed when they see that the smog conceals the view of the Taj Mahal.
