Enclosed in a massive walled complex of buildings and gardens, the Taj Mahal is nearly hidden from the city streets of Agra. Maybe all the better for the Taj to make its impressive introduction. Visitors are led through the complex's first set of gates (foreigners pay 550 rupees, or about $15) where they get only a glimpse of the building. Only by stepping through the second gate does the totality of the Taj come into full view. And what a view it is.
